Clean, safe, quiet Walmart 10 minutes from Phoenix airport.

Just fine overnight parking. Asked security if it was okay. His response, “People do it all the time.” Nothing sketchy. Felt safe. Parked on side of Wally world. Not too much road noise. Semi truck pulled up and kept engine running around 7 am. Nothing you can do about that!

Well lit parking lot, spent multiple evenings here, no issues. Pretty much only Walmart in Phoenix you can park overnight.

Just a heads-up, do NOT park on the petsmart side of the building. I was awakened at 3:45am by a security guard POUNDING on my van to the point it was vibrating stuff on my shelves. He told me “petsmart doesn’t want anyone parking here. You can park on the Walmart side, they allow overnight parking.” So I drove 20 rows, to the other side of the parking lot, and was good until morning. Walmart definitely good, petsmart definitely not good. Walmart has a refrigerated semi trailer that makes some noise throughout the night.
