Our servers on our first Paradise cruise exchanged email addresses with us. The male headwaiter was interested in his new female assistant waiter who was from the same country he was from, but he was too shy too approach her. We "felt" her out to find out if she had a boyfriend back home, and she admitted to being attracted to the headwaiter. We urged him forward, and they had their first date while we were yet on the cruise, and they're still dating eight months later, even though both have gone home for vacation alone at different times. It's great to stay in touch with them!
I was told by CCL that the mailing addresses for their fleet vary by ship since each has a different post office box number. If you'll CCL at 1-800-CARNIVAL and tell an agent the ship that the crewmember is on, they'll give you the correct address.
