I have quotes and am ready to book but I cannot for the life of me commit to November or January.. Everything I am reading states that January can get quite cool at night (even may need a light jacket!!) Now I am not booking a "tropical" vacation and packing a damn jacket!! Other reports are saying that the ocean is still warm even in Jan.... HELP!!!! What is the weather like in Nov compared to Jan?? Ocean temp? Evening temps? hours of light during the day? anything else you can think of...... I sincerely appreciate your input.
