When we cruised from Ft. Everglades in 2006, I returned my rental car to Dollar Car rental at the airport and there was indeed a shuttle that took us from the airport to the port. We used it. At one time I had a very detailed explanation of where to go to catch said shuttle, but since then I have forgotten. You might see if you can get the phone number for the Dollar car rental at FLL and ask if it is still the same there. As Paul said it is very close either way.
