Whitehorse Walmart is going to ban overnight RV parking

"I don't have the luxury of unlimited paid time off, so I'm leaving after work and after dinner, drive for 5-6 hours and park at midnight. The next morning i'm up at dawn, quick bite to eat and drive the rest of the way to a paid campground."
Would you have a problem if I pulled into your yard at midnight to grab a few hours sleep? I'm never in that much of a hurry to start my vacation.:R It is not always the store's decision, often municipal ordinances don't permit boondocking in city limits.
