Geez, not sure I can remember everything.
Let's see. Tipping. 20%!! Where have I been living. We tip 15%, a touch more if really good. And I live in Chicagoland. I hope I'm not screwing people over.
Housekeeping. Never heard of tipping the housekeeper. That's news to me.
When we go to a hotel, like Renee I don't worry about germs too much. We run into germs so much more on door handles at stores and such that I can't panic. I don't unpack but that's because I always worry that I'm gonna forget something in a drawer. I always check the drawers before I leave though. Anyways, I usually turn on all the lights and open the blinds, check the bathroom for cleanliness and check all drawers, cabinets and under the bed for things that aren't mine, etc. Then I sit and read the booklet that comes in the hotel that tells you what services they have and where I can order in. LOL.
