We were there in Oct and the kids had a great time...4, 2.5 and 1. We started out at Breakfastosaurus with Donald, Mickey, Goofy and Pluto and then when the gate dropped we were right at the dino ride (the kiddie one). Got to ride it 2x in a row (no one even there yet). We then headed toward the boneyard and the kids played there for about an hour. We took in the Nemo show which was great relief on a HOT and MUGGY Oct day. My kids really enjoyed the interactive displays (finding stuff in the log, learning about monkeys, etc...people were manning these stations around the park). We met Lilo and Stitch, they weren't thrilled with Bug's Life (my oldest, 4, screamed and cried during the show and we had to leave). They liked playing with the drums. We were only in AK for a half day, so I think that's about all they did...which was actually a lot!
Hope you guys have a great time!
