I caught up with Juan Balbuena on the Carnival Liberty. It wasn’t easy to break Balbuena’s brisk pace as he served drinks, but he paused for a moment to talk. Employed 16 years with Carnival Cruise Lines, Juan hails from the Dominican Republic. He has a son, 25 years old, who works on the Carnival Fantasy, and a 23-year-old daughter back home. If Balbuena appears happy, that’s because he is, “I like to make people happy and to do anything I can do to help them enjoy their cruises, because when I see that they are happy, that gives me happiness in return.”
