Carnivalâs Liquor and Beverage Policy states that guests are prohibited from bringing water, sodas and other non-alcoholic beverages on board that are packaged in bottles.
We know some of our guests are accustomed to bringing on board their own supply of bottled water, so for your convenience, bottled water can be pre-purchased prior to your cruise by visiting www.carnival.com/funshops. Water will be delivered to your stateroom on embarkation day. Bottled water may also be purchased on board by contacting Room Service. Once on board, your purchase is non-refundable; you may take home any unopened bottles.
$9.95 USD (plus an 18% delivery fee) for a 12-pack of bottled water (16.9-ounce bottle/500-ml bottle)
$3.95 USD (plus an 18% delivery fee) for 1 large bottled water (50.72-ounce bottle/1.5-liter bottle)
$20.00 USD (plus an 18% delivery fee) for 8-pack of bottled water (50.72-ounce bottle/1.5-liter bottle)
Carnival carries distilled water which can be purchased either pre-cruise or once on board. For pre-purchase, please contact our Fun Shops department at 800-522-7648, Monday through Friday, 9:00am-10:00pm ET and Saturday and Sunday, 9:00am-6:00pm ET. For purchase on board, please contact Room Service. Should you wish to bring your own distilled water with you, it must be hand carried along with your CPAP machine.
You can also bring in 12 cans of soda per person and adults can carry in a 750 ml bottle of wine. Sodas and wine must be carried in carry ons and not checked baggage.
