We like to leave $5/Day for housekeeping and tip the Bartenders a flat $10/Day. Last day we leave $25 - $50 for housekeeping depending on the length of stay. We also leave the things that we bought that we don't want to bring home... usually a kettle, the unopened beer and wine plus the towels that we bring/buy. Food is always a minimum of 20%. We also leave any OTC meds.
