So I've been asking around and a friend of mine said that the Tower of Terror is getting an update and that they're adding a new floor to the ride. The new floor will supposedly have more ghosts in it. He couldn't give me a time frame or anything on it because he said they're having more problems than expected because the ceiling and walls in the new floor are in really bad shape. Sorry this info is so sketchy and limited but I'll keep and ear to ground and see what else I can learn.
