PiperG-
We were on the Wonder Valentine's cruise in 2/03. We spent Valentine's Day in Nassau. You're right about the weather being relative. Being from South FL, we do feel the coldness quicker than others. I laughed when you said about wearing sweatshirts and shorts because that is normal winter attire for us. There were plenty of people swimming, but we thought they were all out of their minds!
I don't know about your cruise, but on ours; they had a huge heart made out of red and white balloons on the deck by the Goofy pool for Valentine's Day. Then for pictures that night had a special background. Maybe you can remember more and jar my memory.
