Actually, my daughter and her family stayed in one early this year. My grandson is autistic (actually autistic lite we call it, he's pretty cool), and we have a pretty big chunk of vacation club points. Not sure if any of that mattered, or my wife is just pursuasive, but it was very nice being right next to everything for them.
We tried to get in the 100 loop with our MH at that time, but could not, so maybe we just got lucky.
We have seen people coming and going from those cabins several times, and they all looked pretty normal to me ... no crowns, robes or large diamonds that I could see.
Go for it ....
