Noisy pipes prevent sleep
Hotel knows certain groups of rooms have problems where the pipes bang all night long. This started on our fourth night. Got no sleep. Called desk at 1am and were told there was a quiet room on our floor, but we would have to pack up everything, then check out of room and check in to new room, instead of just letting us in to the new room to get some sleep on our last night. And we were very clear when we first checked in that we wanted a quiet room. We pay a hotel for a room to sleep in, if it can not provide that, it has failed.
