Is there still a "No Photo" policy on the Club O beach and is there anyone there to enforce it?
It is probably best to ask those around you if they mind you taking their picture. If they mind, then be polite and don't. If they don't mind, have at it.
I have no interest in taking pictures on Club O beach and would consider it in poor taste to do so....It has been my understanding that many enjoyed that beach because they didn't have to worry about someone taking pictures of them.
