Parenting Question

< We've been at the beach for a few weeks. I love summer and the time we spend here. But the kids are only able to bring a few of their toys and none of their friends. So, needless to say they are beginning to fight. I have 3 kids. 15, 9, and 6. Do you guys have any inspirational ideas so that I can keep them from killing each other? We were supposed to go see a movie today and it sold out. We were there 20 minutes before the movie started and drove 30 miles. Doh! We decided to make it a redbox and chocolate covered raisins day. We have crayons, pens, pencils, tablet paper, lots of books to read for them, board games, playing cards, their bikes and our dogs. That's about it. My girl does have her doll house here. But that's one of those things I played with all the time and she tolerates. LOL Any crafty or cooking things I could do with them to keep them entertained? I'd love to hear your ideas. Please share with me so I have hair when we go home next week! :)
