pilot/flying j overnight parking question

I think the draw to Walmart/Flyin J is they are typically right off the interstate, and you aren't driving 20 min to a campground each way. Pull off the highway, go to sleep, get up and go, no wasted driving. Also it's easier when tired to pull into a big lit parking lot than to try to back into a narrow dark campsite at midnight waking up everyone.

I've never used a Walmart, the only multi day drives we've done we had a popup, and used a hotel, because of setup time. With our TT, I'd use a Walmart.
