Has anyone ever done or seen a Room that changes or Moves while the customers are in it? Other than a "Hellevator". I have an idea on a room that changes - from a Hotel Lobby to a Basement, by having the customers enter into an elevator that seems to take then from the lobby to the basement. (the elevator will only have one door - entrance/exit) Thus only taking up one room. They will enter from the same room they will exit into once the elevator stops. The exit or passage to the rest of the haunt will be different from the way they can into the room. I started thinking about this after realizing that the theme of the haunt doesn't really lend itself to a lot of different scene options.

I know that this idea is not through put friendly, but the haunt it self isn't that through put friendly. Other than through put concerns, any thoughts?
