We have 3 to 4 Pack camp outs a year. We change up the locations each year. Most are state parks (Florida and Georgia) and have a fire pit that we utilize. I'd check with your C.O about a suitable location for a permanent fire pit. If there's not a good place for one bring a portable fire pit. Florida State Parks has a great tool call "One Tank Adventures." It lists all parks within a average tank of gas. At all our Pack Camp outs Families and siblings are encouraged to come. If you fill out your tour plan should help you stay in compliant with BSA regs. Doing it online is easiest because it keeps leader info. We're lucky to have 4 leaders with BALOO training so we've always got somebody trained.
A typical camp out:
1st day - Friday: Arrival and setup - food is on your own
2nd day - Saturday: Breakfast on your own, lunch on your own, Pack Dinner. We usually have a pack event to do (hike, fishing), a service project then breakout in to den activities. Of course, we allow for the kids to have plenty of free time to play.
3rd day - Sunday: breakfast on your own. Tear down and leave.
I think the key to a successful camp out is to have a plan and make sure everyone knows what they are responsible for. Delegate and get people involved. If you're going to have fishing; find your parent that has that skill and put them in charge of it. I like to have a theme for the event. It might be cave exploration, or fishing, forestry, historic tour, map and compass or Native American history/crafts.
