The favorite for me is Epcot. I think it has attractions that are interesting enough to keep an adult entertained. But, if I have to choose for the family, Magic Kingdom hands down

There is just something magical about that place, and it remains no matter how many times I've gone. It's funny because when I was little I thought that there was so much more there, but I guess that's the whole small person perspective thing. It's amazing to see how my daughter's face lights up at seeing all the characters, parades, etc.
