Walmart – Most experienced RVers have overnighted in at least one Walmart parking lot. If for some reason the lot is full, there’s a cheap RV park at Circus Circus down the road (more on Circus Circus later). If you keep a low profile (by not being obvious and setting up camp outside your rig), you can usually sleep in your RV overnight without issue. It’s a boondocking spot, so there are no hookups. It’s not an official camping ground but I see RVs spend the night in that lot all the time. Parking there is free for both guests and non-guests. Strat– The Strat Hotel & Casino has an oversized parking lot located directly across the street from the main building. It’s unlikely, but it is possible to get a ticket. If you boondock in your RV, just know that it is possible to get in trouble. However, many people bend this rule if they’re only visiting Las Vegas for a day or two. In Las Vegas, you’re technically not allowed to sleep in your RV unless it’s parked on an official RV park or campground.
