My wife is Canadian, and went to Cuba on a very inexpensive resort vacation from Montreal about 16 years ago with her daughter. That option is not available to Americans yet. Most of the cruises to Cuba are expensive. This was cruise was more than a typical 5-day cruise, but not too much more. Plus the $75 Cuban visa and the required tour. The Cuban authorities were very detailed in their initial clearance but after that we just came and went as we pleased.
