There are several Florida ports from which you can sail on short cruises. I recommend Port Canaveral, from which three cruise lines sail on 3- and 4-day cruises: Disney, Carnival and Royal Caribbean. They all visit the Bahamas (Nassau and/or Freeport). The nearest airport is Orlando Intl., about a 1-hour ride from the port. And of course, while in Orlando you can also visit Disney World, Universal Orlando, Sea World or any of the many other area attractions.
