Another really cool thing about the sailings from San Juan was the Customs process. They did it onboard in the dining room before we ever got back to San Juan. When they announced that everyone had to bring their key pass, passport and/or photo ID birth cert to the dining room 5th level between X time and X time, I was expecting crowds and a lengthy frustrating process. They had enough staff and hand held scanners that the line never stopped. You passed by each station on the fly as they scanned your info and it was done in just a few minutes. Best system I've ever seen for post cruise processing of passengers. When we did hit San Juan everything was done.
