We don't normally tip housekeeping for one night stays but definitely will for multi day stays. We usually do cruises so the daily housekeeping tip is expected and we normally tip extra during the week with cash which really kicks service up a notch as well.
We go to Bonaire scuba diving for multiple weeks every year and this year it will be for 5 weeks starting March 1. We have known our housekeeper there for over 10 years and make sure to tip her each week. She goes out of her way to accommodate our dive schedule to be in the room when we are out on the water. For the overall cost of the vacation, tipping the housekeeper is peanuts.
