Reddit reviews The Unofficial Guide to Walt Disney World with Kids 2017

Have him watch ALL the videos you can find on Youtube or order a promo DVD from Disney (it's on their website and it's free. Usually arrives in about 4-6 weeks).

IDK what to do about the flying, except maybe talk to his doctor and see if he can't prescribe him an anti-anxiety medication to help with the flight. It can't hurt, right?

Get all 3 involved in the planning...get a copy of The Unofficial Planning Guide to WDW with Kids and go through it with them, esp the 12 yr old. Circle or highlight things that he think sound exciting or that he'd like to do.

I'd also discuss with your wife whether or not tag-teaming would work here. I'd buy a set of decently priced (not cheap, but not expensive either) walkie talkies to use instead of cellphones (because we're the type that leave our phones in the room safe when we travel. We don't want ANYthing from the outside world disturbing us) so that your wife and the girls can be off doing a girly thing while you boys do something more grown up/man-centered (ugh, I know that sounds awful. I hope you understand what I mean. Gah.) and then maybe meet back up later to all do some things together that you want to do.

Are you doing just one park or do you have park hopper passes?

PM if you want...WDW is kind of my "thing". Some people are obsessed with sports teams or celebs. I'm a little obsessed (just a wee bit! LOL) with pretty much everything Disney from the parks to the movies and the company and the man himself. :D
