There is something obscene about wanting to have a good time in Cuba, a place where the citizens are restricted in their liberties and movement. You might be free to travel, but "they are not". Where they are put in prison because of their thoughts and beliefs, you will discuss openly your thoughts and religious beliefs, but "they" will not. Where they and their family can be deported to any region at a moments notice, you will be able to board your plane and go home when your visit is over, but "they" can not leave.
