We've been visiting the island every year since 1973 and Cupecoy has always been illegal for c/o use but at the same time it has always been locally accepted as the ONLY DUTCH beach where c/o was accepted, legal or not. I seem to recall the police being summoned a few times right after the luxury condos were built on the beach there, the owners taking umbrage to their view but I also believe the police came and admonished the offenders accordingly, making them aware of the restrictions of usage but that was the extend of what we heard. There was no punishment and the beach went back to being c/o as it always was. There were stories of similar complaints from the owners of the Blue Mall but I never knew anyone who knew this as fact.
