Two rooms: one where drunken party was last night, beer cans all over, footsteps on furniture, piss in bathroom... anyway, you got an idea. Second room - just to replace coffee pads, nothing else is required.
First room's occupant leaves $5 tip, second - nothing. Which room do you think the cleaning staff would be happy to deal with?
I don't ask to clean my rooms - unless I stay in the same room for more than a week (never happened) I would use the same towels. I can take care to straighten-up the bed. So when I check into hotel, I always tell - no housekeeping needed till I check out.
Works for me.
