I enjoy cigars out on the open deck, usually at night, on the back of the ship.
If the cigar lounge attendant had Cuban cigars he/she would be a smuggler once the ship enters U.S. waters. Not that the Customs Agents are going to raid the lounge or anything but............ ! You can buy Cubans in almost any port in the Caribbean but they are not that cheap. Fifteen bucks for a Monte Cristo or Churchill. And you need to be careful that you're buying a real Cuban.
