Belle,
I haven't done this myself yet, but I have been told the transfers from the ship back to the airport can be done on board during the cruise, and I am counting on this. I have transfers to the ship, but wanted to leave our last day of vacation open ended until we got closer to the date. (and have since decided to just arrange for the transfer directly from the port to the airport. )
Please correct me out there if I'm wrong so I can call the towncars!
Kathy
