What about the money, I can use my credit card?

 

Yes ... as long as it is not American, such as American Express. This is not accepted as a result of the U.S. trade embargo.

Using your credit card is properly advised there ATMs in Cuba do not work with our debit cards. There are to posibilities you take some cash with you from your home country or you can go the a lager bank in Cuba wikth yoy creditcard and passport to withdraw some money. 

When you have a lot of cash don't worry the most casas particulares have a locker.
