We cruised in early Dec. 03. It was very, very cold waiting in line to enter the terminal to embark. It was still cold at Key West, and most people wore coats and jackets. Those who had worn shorts were extremely uncomfortable, and many didn't leave the ship. The pools were empty. It warmed up by the time we got further south. CC was still a little cool, but I found that enjoyable. The water was very cold, but plenty of people still swam.
