We only spent a night at the resort (actually slept in the cave). One thing to know for sure, bring a tarp or tent to cover yourself. We went in March, so with all the runoff from the snow ir was a very wet experience.
I’ve been here twice as a scout so it was a lot of fun to return as an adult leader foe my son’s scout troop.
The sloppy Joe’s are amazing, the exploring was fantastic and physically challenging for everyone. When I was a scout we visited in early January so the cave system was very dry.
