YUCK....you are correct, the covers are not washed every time a new guest checks into the room. I push them down to the bottom of the bed, so they don't touch me. As we just got back from Disney and we drove 3 days to get there, we stayed a few hotels along the way. We don't use the glasses either except when they come sealed individually. Yes, one hotel HIE I think it was had plastic glasses that were sealed one to a pkg...I used those for sure. Getting back to the mouse keeping issues, I'm afraid our trip last year and this year we had some issues. Last year it was a very dusty room and we are talking killer dust bunnies. This year, the shower did not get wiped down the whole 14 days we were there but the biggest issue was the condensation on the windows. Which ran down to the window sill, then down the wall onto the carpet. The carpet was soaked and you could see black mold around the edges where the wall met the carpet.
