When are you going? Off season or shoulder season should be no problem, peak season perhaps.

Have bareboated, anchored, spent the day there on the beach, eaten at the beach bar and had drinks and used the chairs etc but in the summer -- Have never had an issue -- have always asked permission via VHF before landing, have spoken with the Beach Guard (yes, they have them) and cleared with them when we arrived. My perception has always been that as long as you appear to be "a belonger" will be no problem. Sometimes they have preferred we use their towels to appear as guests sometimes not -- wierdly varies based upon the person there at the time. Have never been made uncomfortable or unwelcomed and have many great memories. The beach bar staff have always been cheerful and helpful -- as always, speaking to them, asking their name, being friendly goes a long way. While "legally" they do not own the beach, they can control who uses their stuff -- Good food, great bar drinks, beautiful surroundings -- always one of our favorite stops. Would increase CC limit before the trip......
