All parks are full day parks. I think you guys are grasping straws. If you hit even half of what Hollywood Studios does you'll easily spend a whole day in the park. If you only go to Hollywood Studios and ride Star Tours, Rock N RollerCoaster, Tower of Terror, and Toy Story Mania then yes, it's a half day park. If you only go to Animal Kingdom and ride Everest, Dinosaur, Safari's and Nemo, then it'll be half day. On the same token if I go to Universal Studios and only ride RockIt, Mummy, Men In Black and The Simpsons I doubt I'll spend more than 3 or 4 hours there.
