Called the Walmart in Spokane Valley and was told they do not allow overnight parking because of a city ordinance. Mgr told me the airport Walmart allowed overnight parking for 1 night but when I shopped there it looks like they have a security company patrolling the parking lot so ?? Not sure.

WalMart

Signs are up across this lot . Checked inside and was told they will tow your rig office you spend the night

Still Good

The other Walmart I visited in Seattle doesn’t permit overnight parking.

This store is better than some parks I paid to stay at. LEVEL, smooth RV parking off of Hayford street. Store open 24 hours ( although the hot coffee in Subway isn’t till 7AM). The only improvement they could make is hookups and valet parking lol.
