Our Cabin (it was an "S" suite on the Zaandam) had a hair dryer but according to my wife it was really weak so on our first port she went to a drug store and bought one. She was in the dressing area and tried the new dryer and an alarm went off and the bridge called asking what we were doing. She was told to use the dryer in the main part of the room after that. The first time she tried it, with the slider to the balcony opened, at the exact second she flicked the "on" switch the fog horn blared! She almost had a heart attack!
