Cash tip daily as your housekeeper is not always the same person. I stay at the same place so know the housekeeping staff & what they like. For them, I bring something special plus whatever extras I might think of... nail polish, lotions, etc. I also leave them whatever toiletries & kitchen items I don't want to take back home w/ me. That's usually lotion, hand sanitizer, things like that. After Xmas would be a good time to buy toiletry gift sets as many will be half price. Just unwrap them & pack in w/ your items.
