As mentioned, on many ships there is a retractable line. If there isn't I also recommend getting some heavy duty small magnetic hooks on Amazon (at least 25lbs strength or so probably) and some paracord and use that. The hooks come in super handy for other things too...we hung our key card lanyards on them so they didn't get lost and we'd pass them on the way out reminding us to grab them.
Anyway, no matter where we hung our clothes, they never seemed to dry. So the last time I cruised I brought a small fan in my carry on LIKE THIS . Best decision ever! Worth the spot it took up in my duffel bag. Very light, doesn't weigh much.
I'd aim the fan to where the clothes were hanging overnight, it helped give some nice air circulation in the cabin and also helps drown out hallway noises. We brought a small extension cord to make it easier to aim it where we wanted (in our case into the bathroom) And that was handy as well for the extra outlets to charge phones too. Just a regular extension cord, make sure it does not have a surge protecter.
With the fan the clothes would get dry no prob! You can leave fan on when you leave your cabin as well, just make sure to have a peace of paper or card in the switch by door so your elec doesn't turn off while gone. Our room steward said this was no problem.
Here's a handful of things a lot of new folks neglect:
Read reviews of the departure port (e.g., Ft. Lauderdale or Boston). Some ports are a pain to get to, get in and out of, and have little amenities (seats, bathrooms, parking, HVAC). If your cruise is slightly delayed due to customs or whatever, it can make the start of your trip miserable.
Cruise.com offers some of the best deals and bonuses out there.
As for viruses, wash your hands, be defensive regarding personal contact with strangers, door handles, elevator buttons, and use the hand sanitizer wherever available. Cruises are no better or worse than airlines or college dorms, in the sense that you get a diverse group of people together and people are bound to get sick, but a little prevention goes a long way.
Don't overpack. Take advantage of laundry deals onboard mid-week if you're worried about running out of clothes (often $20 for all you can fit in a paper laundry bag).
Consider getting something like the Belkin 3-Outlet Surge Protector. Rooms on ships have limited outlets, and having power plugs and USB plugs is really useful if you have phones, cameras, ebooks, whatever.
Do the math on drink packages ahead of time (wine, alcohol, or soda), and remember that 15% gratuity is tacked on to all purchases. Sometimes the packages can be worth it, but you may find out you have to drink a lot to break even.
Consider trying traditional cruising first...set dining times, the same servers all week, getting dressed appropriately. Yeah, it may seem a little odd, but it's good to know if you do/don't like it before you pursue a non-traditional approach like Norwegian.
Be careful not to buy drinks in "souvenir" glasses...it's costs you several dollars more and you'll likely not actually want them (some people do, though).
Check out cruisecritic.com for bunches of info.
Don't be shy about exploring the ship and telling people you're a first-time cruiser. You'll get plenty of advice - some of which may actually be useful!
A warning: Once you go for a balcony room, you'll never go back to porthole / interior room again. That said, interior rooms are awesome for sleeping, since you'll never see the light of day.
Don't expect to spend a ton of time in your room, so don't worry about the room quality too much.
Room service (barring certain items) is still free/included and nearly 24-hours on most cruise lines. Order breakfast on a port-day will not get you off the ship faster...going to the buffet or dining room is almost always faster.
Don't be shy about dinner seating...sit with other people...you may meet some interesting folks...that said, don't be shy about asking to be moved if they're complete jerks.
You might want to lurk on the DISBOARDS forums a bit (usually I try not to nudge people off reddit but DCL just doesn't get discussed much here):
http://www.disboards.com/forums/disney-cruise-line-forum.9/
That said, the first thought that comes to mind is ... DCL is probably a lot more expensive for the same itinerary than other lines (including other lines that will have childcare). If money isn't a factor, you can't beat Disney for a family cruise.
The Disney ships are EXTREMELY Disneyfied. That said, if it doesn't drive you crazy in the parks, you'll be fine on the ships. I've only been on the Dream, and I'm both childless and not a Disney nut. It got to me a bit, but it was offset by the cleanliness of the ship and the fabulous staff. We also got a room with a big balcony, and we spent a lot of time there or in the adults-only areas. There should be an adults-only area on Magic, and you could go there while the kid is at the nursery (or whatever they call it for that age range, sorry).
If you do book, in my opinion it's worth spending the extra ten or twelve bucks and grabbing this:
https://www.amazon.com/Unofficial-Guide-Disney-Cruise-Line/dp/1628090502/
Things change very quickly on ALL cruise lines, but the folks behind these books have a very good handle on Disney and DCL. I bought the electronic version and made lots of bookmarks on my kindle.
EDIT: Oh, and if possible you may want to book through Costco. They usually have a fairly large kickback in the form of a Costco cash card. It's basically the only way to save money on a DCL cruise.
I got a set on a cruise on The Love Boat back in 77 (still have them) they are like this and they were decent.
Back in Jan in Hawaii and purchased something simular to these and they are very nice. Almost the same view and smaller, therefore easier to take with you. Think of that consideration when purchasing. Are you going on excursions, can they get wet, what do you want to see.
Our trips have been in late Aug and mid Sept, so we missed out on most of the wild life.
The set I got in 77 was taken with us on our second cruise and they were very good, but the optics in the new smaller one are better.
I guess it comes down to what you are hoping to get a closer look at; Slower items like scenery or whales are not at problem. Birds are another issue.
Command hooks sounds like a very bad idea, but these are the hooks I used on my last cruise, very strong and there are magnets on the same listing that are stronger if you're unsure about these 25lb magnets.
Also, vertical strength (hanging from the ceiling) is gonna be stronger than horizontal (hanging from the wall). With the magnets I got, you only get 1/3 when hanging horizontal, so if your 12lb magnets are the same, you just reduced them to 4lbs, which does sound too light for your wet swimsuit.
Concerning the waterproof phone case, we used a case that was more of a waterproof pouch like this. It is clear on both sides so you can use the camera on it and still see what you're doing as well.
As for waterproof-ness, my phone was perfectly dry and I dove down to at least 10-15 feet to get some video. The only issue I have with it is the water will interact with the screen through the case (as it is touch sensitive.) If you take a video underwater, it may do some weird things like random zooming.
Something I rarely see suggested is bringing a fan for your room. Something like this. depending on your room some can get a little stuffy and having the fan to help circulate air around really helps.

I always bring my phone off the ship to take pictures and stuff. I bought these which worked great around the water. The lanyard part of it was great for keeping it on my person.
Best dry bag I've ever had was by Dry Pak I've also had a waterproof camera case by Dicapac that worked great.
Usually I leave my phone in a bag on the beach, along with my other stuff. I realize that is a risk I'm taking. I carry my ID, ship card and money in the waterproof Dry Pac wallet. Camera I sometimes take with me and sometimes chance leaving it in the beach bag.
I just mean a basic one like this:
https://www.amazon.com/gp/product/B00NY45N5G/ref=s9_acsd_zgift_hd_bw_b24qw_c_x_w?pf_rd_m=ATVPDKIKX0DER&pf_rd_s=merchandised-search-8&pf_rd_r=SWG0CFJ0FEBBPPYZQ62P&pf_rd_t=101&pf_rd_p=b08e95c0-6374-50d9-af9f-1e2411f92014&pf_rd_i=495314
That's what I've brought in the past.
But I'm glad you shared you're experience. I'll definitely be more cautious about that in the future.
There are various types of waterproof wallets or cases that you can find. I've tried quite a few types and most leak. This is the only one I've ever had that doesn't leak and lasts a long time:
https://www.amazon.com/dp/B000BJ7WHE
It is just the right size to hold a couple sea passes, a couple driver's licenses, a credit card and a bunch of US currency wrapped around them. Even keeps things dry when snorkeling and diving 10 feet or more under water.
With other cases: if bills do get slightly damp then vendors still take them and they'll dry out if you spread them out a bit in your cabin overnight.
I always take my phone and leave in a beach bag if necessary. I realize that we're taking a chance on anything we leave in a beach bag but I've never had an issue. They do make similar cases, even the same brand, that fit a phone so you can take it into the water but I've never tried those.
In Europe and places where water is not involved but pick pockets are more of a concern, I carry my passport and most of my money and second credit card in a money belt type hidden pocket worn under my clothing. I carry just a few dollars and one credit card in my wallet so I don't have to go into the hidden pocket very often.
> I plan on taking this with me on a cruise in a month, and am hoping it will be fine: https://www.amazon.com/dp/B00ATZJ5YS/ref=cm_sw_r_cp_apa_i_tUWyCb702R174
This is the best one.

Check them out from the library and flip through.
I just did an Alaska Cruise on RCI and 4 cabins got these and they worked perfectly. The little white seals for the tops were magical.

Seems a bit pricey. Try this one or better yet, the best of both worlds
Not at all a silly question! I asked the exact same thing almost a year ago and this subreddit gave me the suggestion to get one of these: https://www.amazon.com/Universal-Waterproof-JOTO-CellPhone-Motorola/dp/B00LBK7OSY/ref=sr_1_5?ie=UTF8&qid=1482528338&sr=8-5&keywords=dry+bags+iphone. Worked great - and we were highly amused by another young couple on St. Thomas that got into a big argument, pointing and yelling at us, about why they hadn't thought to do this and the husband was now stuck in the water with one hand overhead at all times to hold up his phone.
Thank you. Do you think one of these will come in handy? https://www.amazon.com/gp/product/B01D58DRVC/ref=ox_sc_act_title_5?smid=A1L7F5DL4H71TK&psc=1
​
We are going to be on Carnival and wine is allowed. You're right about snacks, haha. We are going to Disney for a week after the cruise and that's when we need the snacks! No makeup for me as I don't wear it but thanks for the suggestion!

Yes!! Great to hang over the door to store sunglasses, sunscreen, etc. Keeps everything organized and off the limited tabletop space
Our staterooms were rather close and we used one of these to split a single internet package across 4 of us (in two staterooms). This allowed us to use WhatsApp when we were in our staterooms. Funny enough this was also on Enchantment.
https://www.amazon.com/gp/aw/d/B07P5QDQ1B
Enchantment doesn't support in-app messaging via the Royal app. I didn't do much testing but I would be surprised if much else worked before paying. I did not receive anything while unauthed on their Network (no push notifications, no nothing). One thing worth noting is that device switching is easy (username and pin).
I would buy one of the devices I listed and one internet package per stateroom. Make the SSID and password the same for all of them, and carry them around the ship in your bags. Eventually someone will connect to one of these devices and the chat will stay up to date..
I have a waterproof pouch that I wear under my shorts that I keep money and passports in. I leave the phone in the room safe the entire trip. Unplug and relax.
http://www.amazon.com/DP-65-Yellow-Blue-Waterproof-Belt/dp/B000BJ41BE?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_search_detailpage
The best recommendation I ever got (and have used for over 15 cruises) is to bring an over the door shoe hanger. It can be hung over the bathroom door, facing the stateroom. We use it for storing all of our small stuff...playing cards, chargers, batteries, cameras, toiletries, sunglasses, etc.
https://www.amazon.com/24-Pockets-SimpleHouseware-Crystal-Organizer/dp/B01D58DRVC/ref=sr_1_3?crid=33GLB0089WB9L&keywords=over+the+door+shoe+organizer&qid=1563671734&s=gateway&sprefix=Over+%2Caps%2C190&sr=8-3
I keep seeing people put their Phones in these. They arent recommended for more than I think 40 feet underwater, so you should be good. The biggest thing is making sure it stays secure and you don't lose it while on the wave runner.
https://www.amazon.com/dp/B01I1430WQ/ref=cm_sw_r_cp_apa_i_jrNxDbNFE2V0Z
This was just the brand I saw with the highest rating and a high number of reviews. I think the dimensions work but I would double check.
Some sort of waterproof wallet, portable hand sanitizer, portable battery pack (for charging phones/cameras), selfie stick or cell phone tripod, luggage tags
Two most useful items to have, travel power strip and roll up water bottle
https://www.amazon.com/Belkin-SurgePlus-Protector-Charger-rotating/dp/B00ATZJ5YS/
https://www.amazon.com/WINGONEER-folding-bottle-outdoor-mountaineering/dp/B07428NHMM/
Magnets to put on the walls/door. Gets papers off valuable counter space. I already have these and plan to buy these for my next cruise.
I suggest reading Chronicles of a Cruise Ship Crew Member, The Truth About Cruise Ships and Cruise Confidential to get an idea of what it is really like.
The author of the third book I listed has two other books that are also about working on cruise ships, but I haven't read them yet.
We got this to bring on the ship... for booze of course. Others said they had good luck with these, but now I wonder if there will be an issue. They come with a "seal" for each bottle.

String backpack with the following:
You can usually buy just about anything at the port; however, some items are extremely marked up (i.e. deodorant, medicine, etc.)
Instead of tape, get a cord cover something like this: https://www.amazon.com/Legrand-Wiremold-Corduct-Overfloor-Protector/dp/B000BVXVTA/ref=sr_1_5?keywords=cord+cover&qid=1558018774&s=gateway&sr=8-5
Since I like to snorkel I bought a waterproof bag to keep cell phone, ship's card, some cash, passport, and a credit card in when going ashore. This way I could always keep my stuff on me even when I'm in the water. It's so nice to have everything you need hanging around your neck and not have to worry about losing it or it going missing when you're not paying attention. I bought this one and it has served me very well but there are lots out there to choose from.
How many electrical outlets are in a balcony room on the Celebrity Solstice? I've seen a photo from 2016 that showed 2 US outlets and 1 European. Just want to make sure if this is accurate.
Also does Celebrity allow outlet power strips with no (extension) cords and no surge protection onto the ship? Some people in the question/answer said they got confiscated on various cruise lines.
https://www.amazon.com/Cruise-Power-Strip-USB-Outlets/dp/B07BHVKPC3
All of the electronics we bring use USB chargers, so we bring a unit like this. 6 cruises in the past 2 years with no issues so far.
Edit - now without Google Search's referral link...
Buy a super cheap bottle of wine, drink or dump it. Fill it with booze, put the cork back in, and then use this to seal it. If you use a dark bottle they have no way of knowing without opening your wine, which they won't do.
Addressing your comment on sneaking booze on: SHAMBOOZE!
I'd look for one that has UL markings (UL Listed or UL Certified) because they've been tested by Underwriters Laboratory for safety.
See here for an example:
https://www.ul.com/wp-content/uploads/2014/04/ul_markshub_hero_banner_680x285.png
You can even sort by UL Listed cords at some websites like Amazon or HomeDepot.
This one is cheap but is still UL Listed.
https://www.amazon.com/GoGreen-Power-GG-13002MS-Outlet-Strip/dp/B00NY45N5G
Just one example...you could find plenty others.
Frankly though, it has less to do with the power strip/extension cord and more how it's used. They have to be allowed to dissipate heat which many people don't think about. You should never leave a cord coiled or wrapped up tightly and you definitely shouldn't cover it with anything. Let's just say you leave one coiled up and throw dirty laundry over it...the heat running through the cord has nowhere to go so the laundry will heat up and can ignite if it reaches the right temperature. I've seen it plenty of times unfortunately.
I have used these with no issue. I have also used those plastic flasks/rum runners and just put them in my luggage. Also, we bought a fifth in port, put it in nalgenes, threw those in the backpack and got on, no questions asked. I have never been caught/had any issue bringing booze on board. But I haven't been on Carnival in years, since they are known more for the "party ships" they may be more strict about it.
Not sure about Princess but we brought one of these on board and had no problem, on RC.
