The gravel lot behind the Shell station is no longer available. Construction of some sort has just started. There is about six slots at the east end of casino, last drive entrance, but the are slopped fairly good. I found it best to drive around the first entrance then behind the hotel into the lot. Was able to get level enough, front end off ground. Talked to security and the stay limit hasn't changed, three days but if your leaving plenty of money they will happily extend your stay. No registration needed.
