All of the parks have their pros. Here's my list, in order. Some may be surprised as to where Magic Kingdom ranks...
Epcot - My personal favorite. The atmosphere is undescribably amazing. Walking around Future World whilst hearing Russell Brower and David Arkenstone is unmatched, except probably to World Showcase at night, with the paillions lit up and the torches going just before IllumiNations... And then there are the attractions themselves. Mission: Space and Test Track are amazing E-Tickets, and others like Ellen's Energy Advanture and Honey, I Shrunk the Uadience are just pure hilarious. Then there's IllumiNations. It is, IMO, the best thing. Best of ANYthing. Ever. Period.
Disney-MGM Studios - I love the Studios atmosphere, as well. I especially like it atn ight, when it's all lit up, and it's empty because of Fantasmic! and you can walk on RnRC and ToT. Speaking of them, Rock 'N' RollerCoaster is my favorite ride, possibley tied with Test Track, Tower of Terror, and Mission: Space, though. And at MGM, there's Tower of Terror. It has to have THE BEST theming of any Disney ride ever constructed. It's pure genius in concept outcome.
Animal Kingdom - AK is definately an amazing park. Killimanjaro Safaris NEVER gets old, because the anaimals are living and breathing, and something different happens everytime we're on it. And then there's Dinosaur. Dinosaur has got to be one of the best Imagineering feats ever. The ride is absolutely great. I could ride it again, and again, and again. I'm sure my liking for AK will only increase with the addition of Expedition Everest.
Magic Kingdom - Yes, Magic kingdom is last, believe it or not. Why you ask? well, it seems any time we go, the place is crowded, and not just crowded, but crowded with crying children... Yes, yes, I know, that's what Disney is, really, but the other parks seem to have less children, and more things I enjoy. Being a person who goes to Disney World, purely for the parks and not the movies, the Fantasyland rides aren't really my thing. To be honest, I could care less about the characters... 'Cept for Mickey, of course
But MK does have it's fair share of great things, like Space Mountain, Big Thudner Mountain Railroad, and Dole Whip!
So there you have it. Just my two cents. I know some of you are just itching to send me bad rep for putting MK at the end, but can you please respect my opinion at least?
