The good: exposure to new people and pets will be good for socialization - the lack of "nap time" that tends to come with camping will probably make for a tired (therefore "good") dog
The uh-oh: I can see with that many kids, and an outside filled with adventures, that your pup could slip out the dog and be off like a shot in the blink of an eye. I would probably not take him along with the kids until he has what's known as a "bomb-proof recall" and a strong "stay".
We camped once along the ocean a decade or so ago, and a few trailers down from us was a family with youngish kids and (ironically) a rambunctious shepherd. I can't tell you how many times he got out - in his case, he made a beeline for the water to chase waves, so he wasn't exactly a threat to the other campers, but hearing his family of 5 chase and shriek his name as they tried to catch him, multiple times each day, got wearisome....LOL! In that dog's case, he had ZERO recall.
