At one time most casinos allowed RVers to park on their lots for a period of time, maybe even days. If that was the price to get you inside to lose your money to a one-arm bandit, that worked for them. Now, more casinos have added RV parks where they charge you to stay. Yes, you do get some amenities- hookups for one. Once the RV park is in, at least some casinos no longer allow RVs to park overnight on the parking lot.
The RV in the photo is parked in an AZ casino. I was unable to park in one in Indio, CA and had to move in the middle of the night in Prim, NV.
Little Creek Casino Resort, Squaxin Island Tribe’s casino, is the latest to add an RV park. Cost? $35 a night! I think that's high, especially since you are likely to leave much more than that in the way of dollars behind in the casino and restaurants.
The first eight years or so my late husband, Bill, and I were traveling, we only stayed in a campground a handful of times where we paid, other than when we were working. That sure helped the budget. Even in later years, some of the places where we had boondocked had "no parking" signs.
The RV lifestyle is changing. You can still be creative (some would say "cheap!") about parking but it is definitely not as easy. Casinos have always been a place RVers could count on. Those are getting fewer too. Do you still know of any casinos that allow boondocking? Jaimie Hall Bruzenak
