That is impossible for me to answer!
I could easily make an argument for either one. I think the true Disney fanatic needs to experience both, many, many times in their life.
And take a few cruises, too!
And take behind the scenes tours at both, too!
And stay at all levels of Disney hotels while you're there, too!
And try lots and lots of the restaurants, too!
And visit both in one month, putting a cruise in the middle, too!
So much to do, so little time!!! I'm trying to live my own advice.
