NO they don't allow overnights even for vendors. I called and asked security because I'm doing business in the morning, and was told NO WAY.
The parking lot is big enough for RVs as we park our 25' one there when we go but I don't believe they allow overnight as they aren't open 24/7. We have never stayed all night but you can definitely park there.
They have a lot of parking space available for the players only. I do not think they have parking space for RVs and semi- trucks. You may want to give them a call.
