9. Use the “do not disturb” sign on your door.
Every hotel room has its own “Do Not Disturb” sign for a reason. Hang yours on your door and be sure that no one will enter your space unexpectedly. Housekeeping might burst into your room unannounced and find you in the middle of an awkward moment. Just make sure to remove it in the morning, so that you’ll get fresh towels and a clean room.
