We will be cruising April 18th-25th (on RCCL) from Port Canaveral. I've got a one-way rental from the 17th -18th (getting in a day early) and another rental on the 25th. Both are with Avis. I'm o.k. with the departure day, but how would I go about picking up the car on the 25th? Can I call Avis to get a shuttle to pick me up or would I have to take a taxi from the port to their office?
