I don't think so
Just a heads up they do have security drive around at night and overnight. So they will make note of your car being there and it will possibly be tow . They have no idea if its stolen or not and they may call the police to check it out .
Not for 7 days ,parkin is free...
Theres no one there to charge you. I know at some point Walmart was friendly to RVs looking for a spot to park for the evening. Idk about 7 days in a row, or why you would need to do that. If you're meaning your vehicle there unattended I could definitely see it being towed.
I dont c why not. just park in the back away from prying eyes
