1) Animal Kingdom
2) Hollywood Studios
3) Epcot
4) Magic Kingdom
While the MK is the original, I believe it suffers from a lot of stick-in-the-muddiness that prevents Disney from converting what it learned from operating the MK for decades into substantial, positive changes to the park itself. Maybe this Fantasyland rehab will address some of that, but I can see, in Animal Kingdom Park, especially, the realization of all that Disney learned. Putting aside theming, Animal Kingdom is the Magic Kingdom reimplemented capitalizing on all the best intelligence available for creating a magical place where stories come to life.
