I answered the survey and reading this list has reminded me of two more items:

Inadequate lighting in the tub/shower so that when the curtain is drawn I can't see what I'm doing or if I do take a bath, there isn't enough light to read in the tub.

The noise of ice machines, which I can sometimes hear in my room, the noise of busses idling in front of the hotel and delivery trucks idling in the back which I can always hear in my room if overlooking where they are idling, the noise of exterior fans/pumps which I can always hear in my room if overlooking them.
