You are quite mistaken on that point. I've seen similar posts all summer long while this promotion was in effect, and it is generally nothing more than people justifying their own situation - mostly
DVC members (and we are too) who for one reason or another want to believe that DVC is always the best. In this case, for us, paying cash for this promotion was better.
We just completed a week using the free dining promotion - $58/day/person all inclusive for hotel, daily park tickets, a few other benefits...and the free dining. It was a fabulous, inexpensive week for us.
We ate dinner at all of the restaurants we'd never usually go to (besides Ohana) - The Wave, Coral Reef, Les Chefs among others in addition to Ohana. You consider that average food and a subpar dining experience? We always go to Ohana specifically for the fabulous food and exceptional dining experience. We had some of the best dining both food and experiencewise we ever have in all our Disney stays.
I did some quick calculations, and the food alone was coming in at $50 to $60/day per person. So, in my mind, we paid about list price for our meals for high-end food/experience and received free hotel and tickets for the week.
For us, in this case, paying cash for this promotion was much better than using our DVC points.
