No information on hosting but the park is one of our favorites. You have a lake right there with some hiking. 90+ mile paved bike trail runs right though the park. We have used this park to ride several portions of the trail. We have also driven to the Hiawatha trial which is a rails to trial also that has several tunnels, one is long, need lights. As mentioned Spokane is not too far away. Cabela's and a small Camping World store not too far away either.
Will be there in a couple of weeks.
