It is worth noting that travel to the island nation by U.S citizens is still highly controlled and regulated. Contrary to insinuations by many news headlines, Americans are still not allowed to visit Cuba for the purposes of tourism.
U.S. citizens can legally travel to Cuba if they are engaging in 12 categories of activities such as professional research, participating in an athletic event, performing in a concert, working on a humanitarian project or taking part in educational activities.
Previously many of these activities required applying for a specific license and maneuvering a labyrinth of government bureaucracy. Now many U.S. citizens can essentially "self license" if they believe their travel to Cuba meets the legal requirements.
To be sure about how your cruise to Cuba may be affected you should review the current restrictions on the U.S State Department and U.S. Treasury Department Website's.
