Recently (June 2008) overnighted at the River Rock in the Bus parking area. Guards had no problem with our parking alongside the fence, and there was plenty of room for the tour buses to make their turnarounds.
While not ideal, they did accommodate us for the night!
River Rock Casino in Geyserville, CA does not allow overnight RV parking at the Casino but they do have a RV Park nearby that is owned by the Tribe. Check on line before you drive up that hill to the Casino. The area is tight and you may be allowed to park a small RV for a short time (not level) but big rigs will be turned away only to drive back down the hill and find the RV park back towards highway #101.
Picture showing why RVs shouldn't try to park here
See picture sent in by a website member. Parking lot is small and not level. Note that a previous report says that large RVs are turned away but that small rigs might be able to park (small class B?). Call ahead!
NOTE: It was previously reported that there is a campground 4 miles away. The campground's website is no longer active so you should do more research before looking to stay in this area.
