hotels/motels replace their stairwells with elevator shafts.
I stayed at a Best Western in Seattle. They assigned me a room on the 2nd floor. However, I couldn't find a stairwell at all. I asked the staff about it. Turns out management decided to replace all the stairs with elevators in order to "make things more convenient for our guests." It was really annoying (and slower) to have to take an elevator up/down a single floor. I wonder what people are supposed to do during a fire.
Okay, let's hear some others!!
