If you read the opening paragraph of this page http://forecast.mssl.ucl.ac.uk/shadow/ you might be encouraged to celebrate your birthday after the end of November or in another locale, as this year's hurricane forecast is not very encouraging.
What are your interests and what do you expect to do on your trip? Why have you chosen the Caribbean?
Costa Rica, in Central America, is a current favorite from what I've been reading. You might consider an Elderhostel tour: http://www.elderhostel.org/welcome/home.asp
