Beach game?

It's not as hard as you think it is. Last time me and my buddies went down to the beach we just looked for a group of girls. We then conviently started playing beach soccer next to em. Then had my buddy "accidentally" kick the ball towards them so I would have to go an get it.(here's my opportunity to approach them) I make small talk, then ask em if they want to play with us. They happily obliged and within 15 minutes we were back at there beach house chillin, and you can guess what that lead to. After the fact, they wanted us to stay the week with them.(this is during spring break btw) we declined, cause they were pretty boring. All in all just find a reason to approach and integrate them in whatever activity you're doing, keep it laid back and fun, and escalate. Good luck.
