I'm Cuban-American so naturally have very strong opinion about the subject. The cruise lines knew that the travel categories that Obama allowed to travel to Cuba didn't include tourism. The cruise lines asked the passengers to fill out a form certifying under what category they were traveling to Cuba. I can guarantee that nearly every passenger lied as it is very difficult to believe that you go to a port on a cruise ship for purposes other than tourism. I wonder how those certifications/form/visa will come into play.
