I'd have to say my favorite park would be Animal Kingdom, it;s the one park I can go to where I'm not running around like a crazy oerson, and it's so gorgeous that I wouldn't want to.
Magic Kingdom is my favorite because of so many reasons, but mainly because of the Magic. Great rides, attractions, food, etc. It doesn't get any better than that.
I would have to say MK! For one it has the most shade and two there are so many things to do that my family goes there twice each time we go! We love it!!!
