Good Grief !! Six hours to wait for a tranfer ??? Crazy - I would just get
my own taxi or use one of the shuttles services. What hotel are you staying at?? They may offer free transfer from the airport to the hotel. Is RCCL
providing the transfers from the hotel to the pier?? If so, you probably will
have to wait until the bus is full which can be "forever" - again, see if
you can share a cab to the pier. You get on board faster and avoid some
of the long lines. Yes, ask at the hotel desk about shopping and other
attractions nearby. Don't know when your plane arrives but I am sure
you will find something to do rather than sit at the airport - BORING !!
Have a great time.
