I tend to agree with you on this. I think a more fair value calculation would be what you would have paid for typical booking choices. This summer when I attempted to book a one night, weekend, non discounted stay at Pop - standard view - and was quoted $160 including tax, I see value in the real dollars I've paid for my
DVC. The rack rate for DVC units is highly inflated, in my opinion, to help members feel like they are getting a great deal.
For my one night stay, I used Priceline for a 3 star Holiday Inn and got a rate of $45.
