Well, when I was there last the Magic Kingdom was busiest. This, to me at least, usually seems to be the case. Although Animal Kingdom and MGM can both seem ‘shoulder to shoulder’ sometimes, I rarely encounter crowds there like I do at the Magic Kingdom. As for my favorite park, it always has been EPCOT. Ever since my fist trip to WDW, I’ve been a nut for EPCOT. I honestly can’t explain it, but there’s just something about it that appeals to me so much more than the other parks.
