Time Out says
Only around half of the hotel’s 4,407 guestrooms are actually located in the pyramid. These Strip-fronted rooms offer great views and are accessed by special elevators called "inclinators", which rise, like enclosed ski lifts, at an angle of 39º. However, there are compensations if you don’t get hooked up with a pyramid room: the guestrooms in the towers, just behind the pyramid, are larger.
