About our own trash and towel experiences. We make sure we stay out of the room the 4th morning and make sure we remove the do not disturb sign. Usually by the time we return for lunch, dirty towels have been taken away, new ones have been hung, toiletries are replenished if needed, dish soap replenished if needed, and fresh kitchen towels. Trash and recycle is taken away, although we will do that if needed in between. We also make sure our dirty towels are piled in a spot on the floor. There is a little card in the bathrooms about being green and if you don't want them to take yours towels you should leave them hanging on the towel bar. I think some people don't notice this card. I've never experienced having my towels left on the table by housekeeping. That is something that should be taken up with housekeeping if it happens.
