We were on that same Feb. 11 cruise, and the weather was definitely disappointing! We went the same week in 2005 and the weather was perfect so you just never know. The water was too cold for me so I just walked along the beautiful beach. There were lots of people in the water, so I guess it all depends on whether or not you are brave enough to enter those cold waters. No matter what I am sure you will have a great time, and we will be heading back out next year for that same week, keeping our fingers crossed for another trip like that in 2005!
