Have you been (either as an adult or a child)? Did you think it was magical?

I'm going to Walt Disney World (the big Florida one) in a couple of weeks. Been doing some reading, and it's fascinating how there's this whole obsessive community of adult fans who know the entire place in such detail. There's even a dedicated "Ears and Beers" app for finding beer in the parks. I went as a kid but was too young to really take it all in, but have very happy memories from what I can recall (aside from when my brother was scared of the fireworks, so he was crying to leave, and I was crying to stay).
