We (5 people) are flying into West Palm Beach Airport and are cruising from Port of Miami. We currently have Two one-way car rentals but does anyone know of a cheaper way to transfer from sea-port to airport?
The rental car is probably your best bet. Just rent from an agency which has a drop of spot fairly close to the port. I know Enterprise has one just 5 minutes from the pier, and I believe Budget has one located in the Hyatt, which is also close by.
