Appears that you Can still overnight in parking lot for free adjacent to RV park entrance. The RV park is a 5-star ...... if you can AFFORD it -- prices $50-$65 night. Parking area for 'free' is small and limited and must be entered on north side of casino as if entering rv park -- don't get 'stuck' entering casino areas as overhangs will prevent you and turnaround on roadway is limited if you miss the entrance. Nice casino is a pretty good walk and I didn't see any shuttle. I would pass this by for other casino parking in the area (Harrah / Pauma).
