After seeing the post on this site indicating there was RV overnight stay parking, and after confirming this by phone with Grand Villa, we arrived and we’re prepared to spend two days at this location. We spent approximately two hours driving around to locate what might be RV parking to find out by someone parked in the lot that they had rented the lot out for a film production. There was no alternate RV parking other than metered street parking which was very costly. We attended inside and spoke with a senior staff member who confirmed the only RV parking lot was unavailable, and was very matter of fact that the casino parking was only available to hotel guests and those that could park in the parkade, more or less treating us less than a bonafide casino customer.
On the flip side, this is a lovely casino with a great selection of slot machines. We enjoyed the couple of hours we were there, despite the atrocious parking expense to do so.
