We take a number of cruises and on one last fall we stopped in Costa Rica. There were vans that would take you to the rain forest and there was a zip line there. We signed up for the van (not part of the cruise line excursions) with 5 other couples. Long story short. Van's are not allowed on Sunday as they eat into "taxi business". We were stopped on the way back from the rain forest by a police road block. They took the licence plate off the van as we sat there and with a great deal of luck we had a gentleman on the van who spoke fluent spanish and he convinced the police to allow the van to go to the ship but a policeman had to ride as the van would be taken by the police when we arrived at the ship. We understand it would cost the driver $500 to get his license and van back and some other unfortunate problems. We were real lucky as if we could not have convinced the police to allow the van to go back to the ship we would have been left there by the curise line (RCCL).
Lesson learned..
