To answer some of your guys' question,
We're doing it in 4/5 patrols, with about 7 in each.
We don't have anyone with a lot of survival experience, but we do have three or four LNT certified adults.
And like I said above, this would be a patrol based trip.
Since this would be the first time were doing this, I would almost consider this a trial run for future events like this. I don't want to do anything too extreme, like the chicken thing that Horizon said. The scouts that are going to be doing this are from 12-14, and they don't have any survival experience. My plan was to put the basic scout skills that they learn at the meetings (first aid, cooking, etc.) and throw a little survival twist into it.
