We were in Rm 125. The room next door was the electrical room. Every 2 minutes some pump motor, maybe, tried to come on 5,6,7 times, every 2 minutes. Once in a while it got lucky and stayed on for maybe 10 seconds. We could hear it in the shower, with the water running. I thought of calling the desk on the room phone to let them hear it, but that wasn't working. The clerk at checkout said she had worked there 2 years and never knew of a problem. I told her to spend 6 minutes in the room to aquaint herself with the motor rescued from the engine room of the Titanic. The room was clean, though. The hotel was fully booked. Guess we were the last ones to make a reservation.
