All the people in "the background" do a lot of work and should be paid an honest wage by their employer....the ones that directly benefit me are the wait staff and the housekeeper. Any other thing that is done for me I would tip at the time. as for the amount, it is not unreasonable...as a matter of fact, when I leave the ship the amount of tips to the wait staff and house keepers usually is greater than the daily charge, but has been well earned by these individuals. All others are the responsibility of the employer, not the passengers. We don't leave a tip for every employee of a motel when we stay there....as a matter of fact many people do not even tip the house keepers (my daughter and grand daughter have held these jobs and got nothing) and certainly should not be expected to trip all the other staff members that are involved in maked the motel work. It is an individual decision to make...my original question was to find out what I could about NCL .not to start a battle with anyone, nor was it posted for my entertianment.
