I recently booked our transportation from the airport-port-airport, and I checked both the Airport Shuttle service, and RCCL's bus. At the current time, they are both the same price, $19.00(US) each way per person, or $76.00 round trip for two. I, therefore, being the lazy slug that I am, booked the cruise line bus; give them the bags at the airport, and the next time you see them is in your cabin later on that evening. I did NOT check the taxi fare; again Mr. Lazy took over my research. If it's anything like Port Canaveral's bus, they are very comfortable and clean.
