In our last Passenget Contract from Princess (2.07) it states:
"Carrier kindly requests that You do not bring alcoholic beverages of any kind (except wine and champagne) on board for consumption. Alcoholic beverages that are purchased duty free, from the ship’s gift shop, or at ports of call will be collected by Carrier personnel for safekeeping and delivered to Your stateroom on the last day of the voyage. A member of Carrier’s security staff will be at the gangway to assist with the storage of Your alcoholic beverage purchases. A corkage fee of $15.00 per bottle will be applied to wine and champagne consumed in the ship’s restaurant."
IMO, igore it and bring what you want packed in your checked luggage.
