I think Animal Kingdom is the most underrated park. I hear people saying it's a half-day park or they are going to skip it. It's my favourite for a whole bunch of reasons - the attention to detail, the top-level care they provide for the animals (Jane Goodall said that if she was an animal, she'd want to live there), the conservation work they are doing, the shows, Expedition Everest, and of course the chance to see the animals. I am not generally a fan of animals in captivity but I think there is a lot of good going on at DAK.
