There is plenty of BLM and some state land down there. That's why I mentioned it! However, I don't know about accomodations like you are wanting. You may want to look into renting a popup camper or something like that, but you would need more than one for that many people. I don't like to stay in a motel because you lose too much time going back and forth to hunting spots, but you could probably find one in Kaycee.
