We LOVE WISHES. This is a must do !!!!!!! We thought we had a good place to stand over by Tomorrow land.
We also loved Specto Magic Parade and the afternoon parade.
FOOD in MK: Pecos Bill- Very good counter Service- always room to sit down.
Crystal Palace- We loved this Character meal. We thought the
food was good and that the Characters had
good interaction. (dinner)
These are the only two we have tried here in years.
Epcot: We LOVE world showcase and there are some fun things there for kids also. Future world did not hold too much interest for us but there are some things there we like.
