Credit card, pre-paid credit card, US cash, Bahamian cash? Even though we've been to Nassau a couple of times I've never paid for anything other than an excursion and that was through Disney so I have no experience. We're thinking about going to the rum distillery and probably buying some bottles so I'd like to know how I can pay for the stuff. Does the Dream have a currency exchange on board at guest relations and if so will they convert the money back to US dollars for the cash not used? Sorry for the newbie questions but I appreciate any help!
