$18 rate if you mention the billboards on the highway, but $22 otherwise so it's a good deal. Park is close to the casino, pretty level sites, clean, with full hookups (including sewer), no riffraff. Call the casino hotel front desk, or stop in at the front desk to register. Only about 10% of sites occupied when I was there in December.

Big truck stop gas station across the street if you need anything. Casino has a buffet restaurant and another bar to watch the game. Ended up staying an extra night to get prime rib on Saturday. 

Security will drive you back and forth to the casino if you request, but it's only a 5 minute walk.
