We are in the same situation with my son. He loves movies and 4 wheelers at home, but get him in a new environment and he's afraid of everything. He won't even let the characters come near him, or at least he wouldn't last year.
We went 1 yr ago, he was 2 1/2, and he loved the Safari ride at AK, teacups, train, Small World at MK, Mexico boat ride, Living Seas boat ride, and Crush at Epcot. He also like Monsters, Inc (can't remember where that's at)
He was afraid of much of everything else. Nemo had a scary point for him, and anything that started out dark. We tried to be upbeat about the rides, but that didn't help much. We attempted 3 3-D shows and were only able to sit through Honey I shrunk the kids with him.
DH & I had to take turns on lots of things, while making sure he had a good time on the things he enjoyed.
We are going back soon, and hope he is better about it this year. We've taken him to several more movies just here before our trip, hoping to get him used to the dark and the volume!
HTH! Have fun!
