I stayed for several weeks, only leaving to dump tanks at the nearby free dump site at Valley Sewer or fill up on potable water at the Loves Truck Stop, both about 5 minutes away. Made several friends here who also stayed for a period of time.
Feels pretty safe as security comes through several times per day. Dog friendly! I noticed a lot of people with dogs and there is a large dirt lot behind the parking area where travelers and locals take their dogs out to play.
This will be a regular stop for me when I am in the area.
All the comments made in the past still apply. No problem for us to stay in our motorhome for 3 days. Looks like there are a few long term residents. We never checked in with Casino security and we never saw a security patrol in the lot. Makes you wonder if the lot is even part of the casino. Signs still there that say no overnight camping, but it must be some kind of legal disclaimer. We never felt unsafe but in other casinos we appreciated the security presence.
The casino is very nice and the fast food joint was cheap. There is a better dining restaurant that looks reasonably priced and even a Starbucks.
There's a free municipal dump station 5 minutes away, over the freeway, take the first left. Really good dog park on the way to the dump station next to the animal shelter.
