I highly suggest NOT using your credit card off property, but to take cash with you. We usually charge our room charges to a credit card, but we always take cash with us to purchase items off property. We've had our numbers 'lifted' and it is just safer to do it that way.
As for charges at the resort: anything you purchase from the stores are charged to your room as well as spa treatments, private dinners, special bottles of wine, photos. You can pay your hotel bill in cash instead of CC at the end of your trip.
Jet Skis are not part of the resort and are from beach vendors. All dealings with beach vendors will need to be done in cash.
