Thanks for the replies.
How about what makes you happy at each park?
I love Epcot due to cultural experiences, the knowledge one can gain there, the
layout of the park, the food offered in their many restaurants,
the gorgeous grounds, Illuminations, everything!
Animal Kingdom is so unlike any place I have ever been to, it's magical. The beauty of the animals in "natural" settings, the minimal realism of African life, the tranquil beauty of Asia, watching folks come out of Expedition Everest for that last harrowing turn, thanking God I'm not one of them!
The Magic Kingdom makes me happy as I view it as Walt's ideal world! All of the fabulous rides, watching the little ones trying to comprehend the magic, the fact that there are so many areas in which one can whet their whistle, Wishes, shopping on Main St., the ice cream parlor and the unbelievable candy shops that are there!
The Hollywood Studio is lighthearted and somewhat "campy", which is a wonderful thing! Old Hollywood takes center stage, the actors walking throughout the park, the feeling one is waiting to hear "Action", Mama Melrose's restaurant (Disney has great food!), The Muppets, etc.
