Yes, we are at a Walmart. We have stayed overnight in 6 or 8 of these stores. One of them was a bit dicey (Springfield - Mass) and most are not memorable. They are free and we feel reasonably safe. We always shop in the store. It is not a destination but if we want to travel late and get going early it is a good option. This one was very nice. We were alone on the automotive side, WIFI worked in the lot, there were birds singing in the AM and there was a custard stand in the front lot. Perfect.
