We had an outside cabin, and were in port with our side of the ship away from the shore. Drapes were open, and we were changing for lunch (we rarely go ashore) when without warning there was a face looking into our cabin! Yep, he did indeed get an eyeful as who would expect anyone to be scaling down the side of a cruise ship, 75 or 80 feet above the water? He was cleaning the windows. Well, we learned that no matter where your cabin is located, if you don't want to be seen, hang the "do not disturb" sign, and close the curtains.
