The poorly run council camps run for 8 weeks. The well run council camps in my state are optimized -- and monetized -- almost the whole year through. I realize that doesn't work or make sense for every single property out there, but it would for many.
If your state is like my state the resident camps only run for 8 weeks and are about 3x the capacity of what is needed. If we actually got every scout in the state into resident camp for just 1 week a year we'd still have camps running at less than 50%. There are too many camps.
I see your concern and would say that the answer is rewilding the worst camps into adventure bases to get cost to down down while also funneling scouts to fewer resident camps.
One of my fears is that the only concrete idea Leadership has to 'save' scouting is to sell yet more outdoors based land assets to fund salaries. I would bet it's probably one of the few things on this list that might actually be effected.
