My DS loved the parks as a 4yr old. He loved Seuss Landing esp the Cat in the Hat ride, One Fish Two Fish, the Caroseussel, and the water play area there. He loved the playground at Jurrasic Park, Me Ship the Olive, and Pteradon Flyers. He loved going to the Barney show (even though he never watched Barney before or since going). He enjoyed the playground right outside of the Barney theatre. Feival's Playground was great. He loved the Animal Planet show. He got much more excited about the Nick characters at Universal than the Disney characters. To name a few we saw Scooby Doo, Shaggy, Spongebob, Dora, Cat in the Hat, the Grinch, Curious George, Man in the Big Yellow Hat, Woody Woodpecker, The Flintstones and the Rubbles, Shrek, Fiona, Jimmy Neutron Etc. The Jimmy Neutron ride is fun-you may want stationary seating. Woody Woodpeckers coaster is like Goofy's Barnstormer. I would suggest staying onsite for front of the line access!!
