On the rare occasion that I stay in hotel rooms, I put the DO NOT DISTURB sign on the doorknob and I keep it there until I check out of the hotel. I am fairly neat and I make a small imprint. There's a stack of towels. My entire stay I will choose one bath towel, use that, and never touch any of the others. I don't need anyone to change my towels.

I don't need anyone to come in and make the bed or wipe the sink or clean the toilet. I don't like the invasiveness of that.

So I guess that makes two weird things I do in hotel rooms: [1] hang up the DO NOT DISTURB sign and [2] use only one bath towel.
