I have a few cents to add with the others here:
I have also stayed at Fort WILDERNESS AND loved IT
We stayed in the cabins, which actually are mobile homes, however they are not cheap.
If you CAN tent or have your own camper, the campsites are quite reasonable, and the movies are night are a total blast!
I have also stayed in the Disney all-star which is the low-price Disney hotels and they are fine, BUT the walks between the buildings and the bus stops and restaurants can be pretty far for little legs-
Hopefully you’re planning on at least one stroller or wagon anyway.
As for taking kids that young, there are 2 schools of thought.
1. We never know what tomorrow may bring for any of us, so enjoy the moment now!
2. They are a bit young to enjoy some things or to go at a break neck pace, but then, you’ll probably want a nap in the afternoon, too!
A website that is chockfull of Disney info that I LOVE for planning my trips is :
http://www.allearsnet.com I STRONGLY urge you to check them out- they send a great weekly newsletter thats fun to read even when your way in between trips (like me right now).
Remeber to try and see the most "popular" attractions first thing in the morning and the fast laoders and things that don’t develop lines later in the afternoon-
Also don’t miss Mickeys Philharmagic in the magic Kingdom, because the little ones should love that-and it takes in lots of people at once-
Learn about FastPass and USE it to your advantage-it’s great
if the kids get scared, you can remind them it’s only "Movie magic"
and if you ARE going to try and do any other park in addition to Magic Kingdom, (although with only 2 days and such little kids, I’d agree with the other posters to just stay there-
I’d recommend Animal Kingdom, because it’s a little more compact (Epcot is HUGE) and more kid-friendly-but do NOT take the kids on the dark DINO ride (too scary)
Get Bernsteins book from the library and disney world for kids by Vicki someone or other- both very good for planning- also if you want to eat at any sit down restaurants make you reservations NOW, and if you can, try to have a meal in Cinderella’s castle, it’s is SO worth the splurge for the little ones!
