normally always get the 14 day ultimate pass when we visit so we never need to choose between parks and I love them all for very different reasons. If the question was if we were there only for 3 days and you have a no hopping pass which do you not visit as a means of forcing me to choose.... It's tough;
MK, we have to go to, how could we not!
Epcot, used to be on my miss list but now love the world showcase and kids are big enough for Soarin and test track
DHS, love MWM, kids like the shows
AK, just like the animal trails, Discovery Island so when the walkways are crazy suddenly being alone is kind of fun
So if forced DHS as elements of the park can be found (although never the same) in the other parks, but thanks for a none option!
