I visisted Disney World for the first time three years ago. Epcot was the first place we visited. I couldn't believe what I was seeing - EPCOT was a 100 times better than I ever could have imagined and will forever be my favorite park.
I have to go with Magic Kingdom. To me, it is the very heart of Disney World, and has (by far) the most must-see attractions out of all of WDW. Disney Studios has a handful of worthwhile attractions, as does EPCOT. But Animal Kingdom has less than a handful that I consider worth seeing (at least for the time being).
My vote goes to MGM. love this park because it has my favorite rides in it Tower of Terror and Rock N Roller Coaster. Magic Kingdom comes in a close second though.
It looks like mostly everyone loves Magic Kingdom more than anything. That's pretty cool. Keep voting. And I want to know also who voted for Downtown Disney. Not to make fun of them, just to know their opinion.
This is truely a hard one to pick because all of the parks are so awesome. I love MGM though, the rides and the theming are awesome. In second I like Magic Kingdom and Epcot (tie) and 3rd Animal Kingdom. I love the water parks too but I'm more of a ride person and being able to stay at the parks past dark.
