Most of them don't mind. But it would be courteous to ask first, just in case they've got something going on.
Ask Wal-Mart. If it's just for one nite I'm sure they would not mind. They let u know what area to leave it at there parking lot.
There is a sign on the lot that says no overnight parking. A Wal-Mart in another state was sued for allowing it, so now it is banned at All of them.
