I have a fun idea for the Tower of Terror. I wanted to take a sign in a backpack to the ride and bring it out for the picture at the top while I have a surprised expression on my face, you know, like Wile E. Coyote when he falls off a cliff in the old cartoons. It wouldn't have anything inappropriate on it; just something like "yikes" or "uh-oh". Would Disney let you do something like that, or do they not take kindly to such shenanigans? I wouldn't disrupt the ride for anyone else, but that would be a picture I'd love to have.
