I don't know anything about this type cruise--how large the ship line is, where it goes--not interested in that.
On our Holland America cruise in 2010, and the one we booked but cancelled on Princess in 2013, it was clear in their contract information that each person would be charged on their credit card for tips to cabin stewards, dining staff, and in fact the whole crew. It was something like $11.00 per day. If we disagreed with service, we could, of course, go to the desk and discuss with staff and the tip charge would be lowered if necessary. It was explained that the tips were to be pulled and enjoyed by the entire crew, not just our table staff and room steward. When you think of it, there is a lot of other work done by parts of the staff we never see. If they received a decent wage, we wouldn't be asked to tip them, too. But, by automatically charging each person the mandatory tip amount per day , we are tipping the entire staff. The cruise information also states quite clearly, that we can, of course, tip additional to our steward and wait staff if we choose. And we did just that. We calculated how much we had already been charged for tips to our room, counted the number of days on the cruise, came up with a number, and gave an additional amount to the head waiter for our table He must have not understood the result of mandatory tipping, because after we gave him the additional amount which was not a little amount, we got the worst service of the entire cruise. He didn't think it was enough I guess. Welcome to the real world.
