Do not count on your credit card. Yes, San Salvador is one of the is in the Bahamas Island, but it is very small. Don't get it confused with places like Nassau and Freeport. San Salvador is different. The world has forgotten about it and technology has not really arrived on San Sal. The Island lives to a different drum. Places like the Riding Rock and Club Med accept Credit Cards but, if the phones are down, the phones are down and if the power is out, it is out. Yes, there is a bank on the island but just to be on the save site, bring cash. I would not try anything fancy like traveler checks either.
