I just completed a 7 day HAL cruise. $11 per person per day is added for gratuities. I inquired at the desk and was told $4 went to the cabin attendant, $4 to the dining staff and the remaining $3 was divided by back of the house staff. One of my dinner companions said that her cabin boy claimed to care for 28 cabins-- which would put his daily tip earnings at $224 per day..... Now, I think this can't really be possible in that 1) I can't see how one attendant could manage 28 cabins a day and 2) 6k a month seems like way more than I have heard of cabin boys making.
