Cuba is the world's 105th largest country, but despite all logic also one of the most recognizable ones. Think of psychedelic Che Guevara murals, old North American Buicks, dudes with bongos, and old men playing dominoes while smoking great Cuban cigars. This is a snapshot of present-day Cuba.
Cuba has a way of going against the tide. This is all part of Cuba's historical makeup, national dynamic, and inherent beauty.
A class trip to Cuba requires not only a passport, money, and a sturdy backpack, but it also requires flexibility, creativity, good humor, patience, and a healthy sense of adventure. It is not a requirement to speak Spanish, but this would undoubtedly be a huge advantage if you choose to take on group travel to Cuba. It will also give you the opportunity to travel further and dig deeper than the average tourist would.
