Stayed at the New York New York in October, I tried the $20 trick. I already had a comped room but am not a high roller. I arrived at 10:00 AM. When I got to check-in I asked if it was too early to check-in while handing over my ID and credit card with a $20 stuck in between. I was greeted with open arms! I was upgraded to a corner room with windows all around with views on the east and south Strip. Also was the first room out of the elevator.
