I think it's pretty safe to say you'll have temps about 80 during the day. We went on a Caribbean cruise in March 2001 on Dawn Princess. For the 2 weeks before our cruise, they said temps got down into the high 60's, due to a massive front that came down and took in Florida and most of the Caribbean. You'll get these odd things. Bring a sweater and lightweight jacket and you should be OK. Happy sailing! [img]/infopop/emoticons/icon_wink.gif[/img]
Forgot to mention, ship will not be crowded with children, as most will be back to school. Can't say the same for March or April Sprin break.
