I love to book a balcony cabin.  Its great to sit outside and relax certain times of day.  I am aware that the door experiences a vacuum effect and will slam hard.  So when I walk in or out of the balcony I control the door so it does NOT slam.  All I hear is SLAM...SLAM..SLAM..SLAM...SLAM...SLAM all around me.  Do people not know how obnoxious that is.  KNOCK IT OFF PLEASE.
