There is RV parking way in the back on top of the hill that I thought was overflow but may be the area that Sgt Joe says is the cheap seats. It is too far to walk to the casino in July heat so you'll have to wait for the shuttle. Nor does it look like you'll have a view (but I may be wrong). You should call the Riverside RV park and ask them to email you a map--they don't have one on their website unfortunately. If you want the real cheap (free) sites, I see plenty of RVs parked in the casino parking lot without paying. Of course, no showers, water, or hookup.
