We were on our first cruise (3 night Wonder) Jan 27th. It was very chilly. No way I was swimming, the boat decks were breezy and cool. There were some people with winter coats on. Castaway was warmer but water was really cold. We ate lunch under the pavillion and my teeth were chattering. We went to Blue Lagoon on Nassau day. Morning was OK with some sum warming us a bit and we got thru the dolphin encounter. Sat at beach for a bit after lunch but too cold to swim. Beautiful Island though. It then clouded up and started to storm as we were heading back. We booked for April 2006 and I am confident I will be warmer and enjoy it more. We loved the cruise, the shows, food etc...
