Congratulations on winning him over! I, personally, will never understand how someone could not absolutely love cruising. Deep down inside, I believe that people who complain about cruises are the type that would never be happy, no matter what they are doing.
Whenever I get another person addicted to cruising, I kind of feel like a meth dealer...think about it...they get a taste and really love it the first time, and then they spend the rest of their life (and money) going on cruises and when they are not on a cruise, they are almost always thinking about cruising. The only difference is that I have never seen anyone beat up their grandmother to steal her money to pay for a cruise.
