Personally I think the best yardstick is which resort is most difficult to get into at the 7 mo. window.
Not necessarily true.
Demand only reflects popularity, not quality.
Without further comment, just compare the demand for some of the following vs. the 'quality' of the product.
A night at the opera vs. all star wrestling
A fine wine vs. beer
Books: A Classic vs. any Romance Novel
Movies: Spiderman or Star Wars episode III vs. almost any other movie. (Let's face it, those two movies are fine entertainment, but do they truly reflect GREAT filmmaking?)
Now my interpretation: The Demand for the BWV's is actually for the amenities around the resort within walking distance, and NOT for the villas themselves.
So in my opinion, if you are comparing villas to villas, OKW wins hands down. However if you are comparing resort area to resort area, then BWV wins hands down. It's the area around the BWV that drives the bookings, not the villas themselves.
But you could get that same resort area by staying in the BWI, or YC/BC, or Swan-Dolphin (to some extent). The question then is for many DVC members is, is the trade-off in villa accomodations between OKW and BWV worth it for the trade-up in resort accommodations around the area. For many that answer is yes. But it doesn't mean that the BWV's are better than OKW. Nor likewise does anything about OKW villas make them better than BWV.
The point is that they are different enough from each other that it's more of the apples to oranges comparison.
Face it, is all star wrestling really a fair comparison to Opera? There's no similarity at all, so comparing the two in any way, by popularity, by artistic presentation, by cost of ticket, etc. is all meaningless.
Maybe it'd be best if we'd all let these comparisons just die once and for all. All the resorts are different in their own respects. For some the room is more important while for others the outside surroundings are more important.
And for prospective buyers, the most important advice I can give is that if you're confused by all this, then go to WDW and check out each resort yourself, and decide what's best for YOU!
