The elevator at the hotel where I stayed in Paris was one of the strangest elevators I’ve ever seen in a hotel.  There are no buttons inside the elevator except for the open and close door buttons.  You select your destination on the panel outside the door, and then the little LCD screen on the top shows you which elevator will take you.  When the elevator door opens, there’s a tiny set of lights showing which floor numbers that elevator will stop at.

Weird, but effective.  Although sometimes that elevator got really full.

Have you ever been on an elevator with an unusual configuration?
