Travelers to Cuba from the United States should be aware that U.S. bank issued credit cards and American Express are not valid in Cuba. The hot spots for future Cuban growth in tourism are Cayo Coco, Cayo Largo, Varadero, and, of course, Habana for its historical sites. Other lovely places to visit include Santiago de Cuba and Trinidad. To be honest, all of Cuba is beautiful. Drives through the countryside are rewarded with wonderful scenery around many corners.
Cuban housing is a problem for the population.
NonCubans can not buy speculative real estate at this time The Cubans remember when much of the land was held by large landowners and foreigners prior to Revolution led by Fidel Castro. The Cuban government is amenable to joint venture possibilities in real estate and other business ventures. The cost of living in Cuba varies upon the location. Dollar denominated stores offer the most variety of goods and services. Of course, you pay higher rates than if you are willing to go to the local farmer's market.
