That’s good to know. For me, it is an incentive to upgrade. On our last Celebrity Cruise they gave us a check to sign for the difference every time we exceeded the classic package limit. It seemed like a hassle for the bar tender, especially when they were busy. And the check had a place to add an additional tip and tally it up. Did anyone else feel a tiny bit pressured to add something on top of the 18 % gratuity already automatically added to the extra cost of the drink?
