Everyone should visit Orlando at least once in their lives, even if they don’t have kids. Of course, once you go, you probably will never want to go back because it’s so completely geared to tourists. There’s not a whole lot to do (from what I’ve seen) except sleep, eat, shop, and be entertained. While that will more than fill up time and make it quite memorable (especially if you have kids), all of it is hell to coordinate unless you shell out some bucks for a package that includes everything pre-coordinated including reservations. You’ll have to stick rigidly to someone else’s schedule the whole time you’re there, but it’s really the only way if you want minimal stress.
