I can never believe how inconsiderate people can be, especially at night when they return to their cabin very late. We have put a note on the door hoping they respond. However, the last cruise we were on, it was crew that were guilty. Their door was across the hall from ours. At midnight one night there was a mighty slam that woke us up. I phoned down to Guest Relations and told them the crew should be more considerate. They said they would look after it. Well, it happened again 2 hours later. I guess they had returned from security duty. We phoned again and I think we woke up the GR person! Anyway, next day they had a repair man up to adjust the latch and he fixed the problem.
I was taught not to slam doors when I was five.
