Where is a good place for a vacation in the Caribbean or Central America?

My boyfriend and I are 22 and 23 years old, and trying to plan a vacation for March 2009. He wants sun and beaches, and I want adventure and culture. I would also prefer a place that is not totally swamped with tourists. Any suggestions?
What is it about the place you suggest that makes it a good place to visit?
