A few years ago me and a biggish group of mates took along the then 10 year old daughter of a friend. She'd been the two previous years, with her mum, so knew her way around. Inevitably she would sneak off and go exploring on her own. One afternoon she showed up back at our campsite followed by two policemen. She wasn't lost, but they'd obviously thought she looked a bit young to be on her own, and followed her back to make sure she was all right. And then one night she got up and went out by herself quite late, and some steward took her to the welfare place, from where I had to retrieve her at around 2am.... it's a pretty safe place really for kids. It's difficult if kids are too old to be "never let out of your sight" but still small enough to worry if they go off exploring for too long. We used walkie-talkies, which worked quite well, although you need a few sets of batteries to last.
