Can I bring my small RV and park it down in the mall parking lot for just the final night w/o getting in trouble? Are people paying to park there? Does mall security shoo them out? As an alternative is there a nearby park or RV campgrounds?

There's a Walmart not too far away, maybe 5 minutes from the show site. I think they still allow over night parking for travelers, so you could ask there. Have fun at the show!!

You cannot park overnight at the mall, but there is RV parking at the host hotel

Don't know. But just call them and ask. I do remember seeing RV's there before - but don't know if they were just in for the day(s).

mall security will shoo them. for sure
