To us it is so much more than a theme park. It is a complete escape from our ordinary stresses, and time to just make memories and let go for a minute. I get misty eyed as soon as I first see the castle, and teary again when I turn and take that last glance at it. I get to be a kid, and see my own kid get swept up in the experience. We get to go on rides from our favorite movies, see shows, learn about other places and cultures, and we usually end up meeting some really cool people from all over the world. And where else can you fly to Mars and then visit Norway?
I always compare leaving the park to the movie Somewhere in Time. When Christopher Reeves sees the penny and is ripped back into his own reality, that's what leaving Disney World feels like. I guess if you have been infected with the Disney magic (which I definately have), you may tend to see the whole thing through rose colored glasses. So be it though. I'm on the "it is so much more than a theme park wagon."
