I need help picking up girls

I'm at the beach and I need help picking up girls, plus there are a few problems that are also in the way. First problem is that the girl is either walking with her friends or her family and I have no wingman to occupy the other girls, and if she is with her family I don't know how I would talk to her. Second problem even if they're alone I don't know what to say to get the conversation going. Can you help me reddit???
