We were literally trapped on our floor, because the elevator would not go anywhere while the doors kept malfunctioning. They wobble like crazy, and one elevator kept opening and closing the doors after we got in on floor 19, regardless of what we would do. The elevators to our floor (19) were positively terrifying, and I am not a shrinking violet (I like to scuba dive, am adventurous, etc). Eventually we went to a kiosk and printed room keys. About another dozen tries later, the door miraculously opened. When we finally got to our room and tried the digital key on the door it appeared to work for a second (flashed green), but the door would not open. We went to different elevators in our designated elevator bank (there were four in our designated bank, #3), and finally a fellow guest helped us by using his key and pressing our floor number. We tried them over and over in the elevator to no avail. Sadly, the digital room keys on the app don't seem to work at all. We decided to download the app and check in and get digital room keys. First of all, the enormous wait at check in are annoying. We laughed at the line in the movie, but thought it was a little harsh. We have stayed at the Luxor in the past, even after Clooney called it a sh*&ole in' Up in the Air'.
