I was pricing rental cars myself in Port Everglades (We sail on 3/6 on the Volendam!) and all the major rental companies (Hertz, Avis, Dollar, Budget) told me that they would REIMBURSE clients for Taxi fare. So, in the end, you wont pay anything if you bring your receipt to the rental desk. Also, we're paying 65.00 per night for a CONVERTABLE from Dollar (In March) which is Phenominal! Enjoy your cruise!
