I think it's a great idea! I do cruise solo simply because my hubby will only go once a year. I'd go every month if my paycheck would let me. I know they don't like singles because they believe we don't spend as much as a couple. However, they've not seen me in the casino
I normally lose enough to pay for another cruise, sometimes 2. Singles are a huge market. Now, I'm not saying that there should be swinging single cruises, just a normal cruise that I can go by myself and enjoy the same ammenities that I enjoy with my husband. The ocean, the ports, the food, the snorkeling, the casino, and the marvelous shows!
