This is harder than I would have expected it to be.
1. DHS (By far the best Rides)
2. Magic Kingdom (I can't explain it, the rides aren't great the food isn't great, but I just like to be there)
3. Epcot (some good rides, great food and drink, lots to see and do)
4. Animal Kingdom (Like the safari, EE, some of the shows. Dinoland is bad, but I just don't hang out there so no biggie)
The four are really close as far I am concerned any could take the top spot depending on my mood.
