I plan to go this summer. No fear. Know of too many others who have taken numerous trips to Cuba. There is virtually NO crime against tourists as the laws are far more punishing if the crime is committed against a tourist.
Cuba has been described to me as being stuck in a time warp. It does not have the tacky build up of other resort destinations. Most hotels are going through major overhauls.

Just bring your US greenbacks. Fidel loves them, so does the country.

To get there just travel through an intermediary country like Mexico or cananda.

The US is the only country that has a problem w/Cuba.
