How about what happens at Fantasmic? Do they route people backstage on a regular basis when the show is complete? I've only experienced it myself once, but I've only seen that show twice, so I'm probably not the best to comment.
I see what a lot of you are saying about the Magic Kingdom parks. But, I don't really see the need with Fantasmic. That was a new addition to the park with a set number of guests in it at one time. So, why wasn't it designed properly in the first place?
