staying overnight at walmart
we've stayed at walmart a lot of places , and some do have signs saying no overnight parking, some we've stayed at with signs are Apache Juction AZ, St.Augustine Fl. even though the signs are there they still have overnight campers there, we never had any issues at these , when you think about it, with the signs in place, this most likely would release them of any liability in the event of any accident or foul play, robbery etc. and if you ask the store manager if it's ok they most likely are instructed by their superiors to reply NO , A Yes could automatically make Walmart liable in case of an event.
