When we went on the Radiance, the people that took the transfers were in a line a mile long waiting to get on the buses. We were last off the ship because we had a late flight and we still beat almost everyone that took the transfer. Best bet take a taxi, even if it means carrying your bags a little further, you will be happy to get off the ship and pass up that line, plus (in PR
anyway) there were several baggage people willing to take your bags and show you to a taxi. Another advantage..since you beat all those people you get in a much shorter line at the airport too!
