Sounds like a nice roomy area...maybe a good site for a group hang.
They have several sites that can host 25 people per. The group sites are only a 4-5 mile hike in from the lot (or a 2.5 mile kayak / canoe / boat trip)

Its not quite car camping... but it isn't backpacking either...

I'd be down for a hang there 4 sure

Glad ya'll enjoyed my trip!
