I asked the same question a few days ago and was told Royal Carribean has excursions after the cruise. They are bus tours that last 3 to 6 hours and take you sitghtseeing with your luggage and end at the airport. The ones I saw for my trip in Dec. were Old & New San Juan, Bacardi factory and the Rainforest tour. I was also advised to give myself plenty of time at the airport because it can get very busy on Saturdays. The excursions are listed on the RCI website. Maybe someone else has alternatives, it might be nice spending the last day of vacation at the beach!
