I've heard you can stay ...and casinos, too.
Different casinos have different rules.
The Chinook Winds casino in Lincoln City OR, used to have a lot where people could camp for free for as many nights as they wanted. People started abusing the privilege, staying the entire summer, setting up elaborate camps, so the casino put a stop to it, changing the area to day use only.
The Three Rivers casino in Florence OR now requires a club card to overnight in their RV lot.
I think the Cher-Ah casino in Trinidad CA has changed their free camping policy, but I don't know what to.
The Blue Lake casino near Eureka CA charges.
Casino del Sol, southwest of Tucson, used to allow unlimited RV parking in their lot, but they put an end to that after they built an RV park next door.
The Q casino near Los Algodones used to have free RV parking. Now they charge.
The Cocopah casino between Yuma and Somerton AZ charges to use their RV lot. So does the Paradise casino on the north side of Yuma.
And several Las Vegas casinos on the Strip used to have free parking (I liked the ground level behind New York New York—tall enough for the van) but they're all switching to paid parking.
So the free overnighting thing isn't universal, particularly in popular vacation and snowbird areas.
