You should bring bedding including a pillow, sheets, and a blanket (or a sleeping bag). Also bring a flashlight or headlamp and a towel if you'll want to shower there.
Each separate "village" has 5 cabins and a central shower house. So, there are bathrooms available, but not in the same building that you'll sleep in.
Unfortunately, Cuivre River State Park will not allow us to set up tents in the group camp area.
When people RSVP as sleeping over, we will ask whether you'd prefer to be in a "quiet" area that will be more suitable for families with kids and will be further from the party. From that, we will ensure that we have enough beds available for everyone wanting to stay. We won't reserve/assign beds beyond making sure we have enough!
