Chase away frugal cruisers, no.... The POA is costing more than a Celebrity cruise=)
Chase away informed cruisers, maybe.
I think it would be a good idea to email Stephen from the Pride of Aloha problems thread to understand how the "service charge" really works. As a matter of fact it will again make the cruise more expensive because none of the staff gets any sort of cash compensation from your mandatory "service charge". We'll see how "satisfied" and joyful the travelers are when the staff has no reason to take good care of them.
