For some reason I am getting drawn into this, even though I don't care about it either way. I think everyone has their own guidelines for morals and ethics. What works for someone else might not work for me, but it's not my place to push my own ethics on to someone else.
What's intriguing me is that it sounds like the merchants ask if you have
DVC. In the California resorts, they ask, "Do you have any discounts?" I know that my Inspire Key has the highest discount so I offer my Key to be scanned. If I didn't have the Key, I would say that I have DVC and the credit card and ask them which they want to see. I've never been asked if I had DVC, so it's kind of blowing my mind that it's a normal question in WDW.
