This is totally an aside, but...
Comparing to rack is probably overly optimistic, because Disney often offers discounts at the various
DVC resorts. However, comparing to "renting from an owner" is probably overly pessimistic, because owner rentals are less flexible than booking with owned points. So, a "fair" comparison is probably somewhere in the middle--say something between 70-80% of rack, inclusive of taxes. Which end of the range you use is probably best determined by the answer you are hoping for. ;-)
