Hi Kyra (my daughter is Kira

) Welcome, and best wishes for your son's continued improvement. Does he have any particular medical needs you need to address? You can probably find info on just about everything at the Disabilities board here.
My friend stayed at Port Orleans last year with her 7 and 9 year old boys, and loved it!!!
Well, for starters, will you get there before or after his 10th birthday? It does matter, because as I understand it (someone else please verify) if you get there before he turns 10, he still counts as a "child" not an "adult" in terms of both park tickets and the meal plan.
Are you considering the meal plan? I think it's great; we did it last year with our 3 kids and got to eat in a huge variety of places we otherwise would have skipped. It runs about $40 per day for an adult, and $10 per day for a child, for a counter service meal, a table service meal, and a snack.
OK, some general things your son may enjoy:
FOOD:
- the Coral Reef in Epcot-- one entire wall is an aquarium. It's gorgeous! We loved the food too.
- Character meals-- my kids enjoyed Chef Mikey's-- all the characters come up to your table for autographs. You can also do breakfast with Stitch at 'Ohanas in the Polynesian (easy to reach by monorail from the Magic Kingdom) I'll leave out all the Princess stuff.
- We loved the steaks at Le Cellier in Epcot; my 10 year old son is a huge steak fan. Reservations can be very hard to get, but it might be worth a try.
- This year, my son really wants to try Sci Fi drive in in Hollywood Studios.
- One way or another, try to get to the Polynesian (either the fast food Captain cooks or Kona Cafe)one morning for Tonga Toast. It's French Toast stuffed with bananas. Probably a bazillion calories-- and a bit too sweet for my taste-- but I bet your son loves it!
OTher:
- If he's a dinosaur fan, be sure to spend some time in Animal Kingdom. My kids were a bit too freaked out to do some of the dinosaur stuff there, but take a look.
- Also at AK, we loved Kali River Rapids (be warned: we got soaked! But that was the fun part!!) and the Safari. The kids aren't roller coaster fans, so we skipped those.
- Epcot: RUN, do not walk, to Soarin'. It's beautiful and fun-- like hang gliding, but you're actually only 15 or 20 feet up in the air.
- Depending on your son's medical limitations, also look at Test Track and Mission Space (green is the tamer version.)
- My kids also loved the rides in Norway and Mexico, Norway in particular. They also loved the Imagination pavillion and spaceship Earth.
Magic Kingdom:
- My son LOVED the Indy Speedway. Other big hits included Pirates of the Carribean, the Haunted Mansion (fun, not scary), Buzz Lighyear, Peter Pan's flight, the Jungle Cruise (my 10 year old son LOVED all the corny jokes) We also MADE him go on Small World, and he enjoyed complaining about how he couldn't get the song out of his head.
I botched our day at Hollywood Studios (got there late, everyone was cranky...) But get there early and go RIGHT to Toy Story Mania, as quickly as you can!
Misc: Be sure to see each park closing at least once. Wishes at MK, Illuminations at EP, and if you can get in , Fantasmic at HS. They're incredible.
- One day, when the monorails aren't packed (translation: not first thing in the am or last thing at night) ask if you can sit up front with the driver. You may have to wait for the next train, but it's cool!
- Be sure to request a wake up call and let him answer the phone.
- Ask at the desk in your resort for a "First Time in WDW" pin. It may get him a bit more personalized attention.
OK, that should get you started!
