Not sure about the layout of other deck cabins, but I am not worried about our exposure on deck 7. The entry into the cabin is basically a narrow hallway with most of the cabin further down and around a sort of corner so to speak. Limited view for sure.
On any ship, we have opened the cabin door to other pax and crew members walking by of which could see in if they wanted to.
It is the noise of the elevator and the foot traffic I was worried about, but am very relieved to hear (thank you @Squawkman) it is not a problem. 🙂
I will just try not to open the door naked. Oh yeah, that will scare them away! 😱 😄
