In addition, American cash, credit cards issued by an American institution (e.g., Amex, Citibank, MNBA, AAA, CAA) and pre-paid Canadian or American credit cards are not accepted in Cuba.
Cuban Spanish is Cuba's official language, which is associated with Caribbean Spanish. Haitian Creole is the second most popular language in Cuba.
