Surprisingly, a lot of people think so. Sure, there are kids everywhere, it's hot as hell, the rides are designed for children and the lines are heinous, but it is a magical place after all. (Full disclosure: I've never been to Disney World but I imagine since it's filled with children, everything is vaguely sticky. Is it sticky?)
There has been much debate about whether or not you should go to Disney World without children or if you should bring children who are so young they'll never remember it. One woman went so far as to suggest that people shouldn't be allowed in the park without a kid and that is truly insane.
