Room on common wall with service elevator
On check in we specifically requested a room away from the elevator banks. We checked in early so there we still many rooms to choose from. When we went to sleep it sounded like a snow plow was operating in our room - we realized it was the service elevator. This went on the entire night. It turned out that our room and the bed were on a common wall to the back side of the service elevator. It was too late to change rooms. It was the worst night I have ever spent in a hotel room.
