We have attended rallies at the RV park as well as just staying anytime we drive north from Texas. If you are a regular at the casino, they send you free nights in the hotel, which you can use in the RV park. The pavilion is complete, as well as a new swimming pool. They also have a big rig parking lot next to the casino, partially paved, partially gravel, with no hookups, but the shuttle bus drives through on its regular run. As it is about a mile from one end to the other, this is a nice feature.
The shuttle service can be a bit slow, but delivers to all areas of the casino. The RV park is still clean, pristine and level with full hookups.
