Great place to stay for the night as you're traveling through the area. The casino allows free overnight parking for RVs for one night, and only allows 3 RVs per night (their parking lot is relatively small). We stayed here on a Saturday during Labor Day weekend and were the only campers overnight (other than a couple of cars who just probably stopped to sleep who came late and left early).
You register inside with the security guard, they take a copy of your driver's license and your information, and you're set for the night. No setting up of camping equipment (chairs, bbq, etc) outside your RV. They have a nice bar and grill inside, but no meat free options, not even a veggie burger. The only meat free items on the menu are cheese quesadillas, fries, onion rings, jalapeno poppers, and mozzarella sticks. They do offer free popcorn, soda, and coffee though, a nice treat.
The casino is in a beautiful and quiet area (we watched a mountain lion sauntering about the field across the street in the late afternoon!), but the clientele is a little rough and rowdy. We never felt unsafe, but they were definitely late night partiers who continued the party in the parking lot after the casino closed.
Casino also has shows sometimes (not when we were there).
The loud guests may have been a one off, but still we're not sure if we'd stay here again, unless we were really in need of a place.
Verizon phone was roaming on the US Cellular network, and the att phone was fine.
