Which is dumb because they want you to reserve and re-use towels.
If you can't make your bed as an adult there is something wrong and not having your bed made is not going to kill you.
For me, I'm lucky that I have a mainstream business so I can use that when traveling. Show my site, my business cards, and business visa that will then be used a competing hotel. And I have no problem doing that.
I would make make such a stink, they would be afraid to accuse another woman again. You just have to switch it around on them.
Plus, I use the actual drawers and put my stuff away. Even if staying a single night. It's a thing for me. So none of my stuff would be out and visible if anyone came to the door.
I also have an "add-a-lock" which works on hotels to keep the door locked inside without using their latches that the staff can remove. There is no knock then enter or attempt and hit the latch. The door just doesn't open at all.
If you are touring, maybe set up a wix email or something cheap with a throw together site and some vista print business cards. I always ask if they have a business area and if they have a place to leave cards. Some hotels have draws for things.
Also, I use the amenities and make sure I'm seen using them. "Hookers" hide. So I don't hide.
