We spent the night in a Walmart parking lot. It was the first time we got the infamous late night knock on the door from security asking us to leave. We explained that we’d received permission (I always call ahead to confirm that the store will allow us for one night), but that didn’t appease the man. I had to bounce back and forth between the management at Walmart and security and finally got an agreement that I didn’t have to wake up the kids to move the RV at midnight. We were allowed to stay.
