Does anyone know if you can use your credit debit card on the cruise ship ? And if you do, do they charge a percentage ? I know most restaurants are included with the cruise but say if you purchase a drink at the bar if you didn’t get the alcohol package or if you purchase something from inside one of the stores on the boat. I know before you cruise you have to provide your credit card information anyway so they can charge gratuities but I don’t want any hidden fees.
