I travel full time in my work. Currently going to Houston 5 days a week staying in a hotel but soon to take an apartment. I too strip down as soon as I can and open up the curtains as both contribute to my relaxation. Hate being closed in a hotel room. I don't care if someone sees me but also do not want to cause trouble. Not an exhibitionist. So I am prudent and close the curtains if the visibility is to exposed the the casual observer.
Last week I was in Nashville TN staying for a few nights due to work. One afternoon I returned to the room before housekeeping had gotten it done. I saw the lady in the hallway and informed her not to worry about my room that day. Once inside I got outta clothes quickly. A few minutes later she knocked on the door. I answered it nude but was behind the door. Again letting her know not to worry about it. Then I notice she had turned red and kept looking at the wall. When I closed the door and turned I notice the full length mirror I was in front of. She did give me a big smile later when I was dressed to go eat.
