We have a family of 5 and what we do is take those little frozen pops/chilly willy things with us. When we go to the pool,ocean,waterslides etc then we just put 4 or 5 beers, 3 or 4 gatorades, a couple juice boxes in the cooler and put about 15-20 freeze pops on top of them. They keep the drinks cold all day and the kids can eat a couple pops wherever we are. Then when we get back to the camper we just throw them back in the freezer and freeze them for the next day to repeat the process. One box usually lasts the whole week while we are using them as refreezable ice and eating as popsicles...best of both worlds!!!
