Yes, they allow overnight RV parking BUT NO DOGS ALLOWED anywhere in the casino area. We arrived at 2 PM and found our way up the hill to the RV area (not really marked). We could see the RVs on top of the hill overlooking the casino so we wound our way through the casino grounds and up the hill.
We parked and Jim took the dog for a walk to to talk to the Security Guard. He was told "no dogs"- not even in the cars or RVs. BUT we could stay- just be quiet. So we went about our business. At 10:30 PM when Jim took Angus for his last walk a different Security Guard told him we had to leave "immediately". Did not make any difference that a Supervisor had told us we could stay and that it was now 11:00 at night. SOOOOO we packed up and left. Fortunately it is close to the 210 freeway and we knew our way.
About the casino: large - no penny slots - buffet $14.95 ($1.00 off for card holders) was just okay. Shuttle service up and down the steep hill. New card holders get a deck of cards. 3 cocktail lounges. Busy card room.
