These are my two favorite theme parks! I think I have to go with Animal Kingdom. The food is delicious, they have animals, they have some of the best rides: Flight of Passage, the safari, and Expedition Everest, and the theming is just beautiful and relaxing.
I will never turn down a trip to Animal Kingdom, as it hosts my favorite Starbucks on Disney property, Creature Comforts....EPCOT has some really good food, and my favorite rides such as Spaceship Earth, and Guardians of the Galaxy.
