Cruising October 31, 2009, Out of Jacksonville, Fla. 5 Day Cruise. Ports are Halfmoon Cay and Nassau, I have been trying to find out out what the water temp will be like at this time! Would appreciate any response! I know a lot of you folks have been addicted to cruising longer than I have! I still have lots to learn! Any Advice is appreciated! Never been to Bahamas. Only been to Key West & Calica, Mexico, on first cruise! The second Key West, Grand Cayman & Ocho Rios Jamaica. Both were great! Thanks For your help!
