BWV is simply a more expensive neighborhood. This statement is not meant to stir up a debate on which resort is better. They are both GREAT resorts.
Looking at a different perspective...I'll try to explain my observations when comparing each size villa (square footage) within a particular resort. A pattern seems to appear.
For example at OKW a 1 bdrm gets you 35.33 sq ft per point, a 2 bdrm gets you 36.58 sq ft/pt and the GV gets you 37.19 sq ft/pt. Only a 5.3% spread. Not really much of a difference, meaning the number of points needed for a particular villa appears linked proportionally to the size villa (square footage).
In the case of BWV a 1 bdrm pref gets you 20.12 sq ft per point, a 2 bdrm pref gets you 23.27 sq ft/pt and the GV gets you 21.45 sq ft/pt. An 8.4% spread. More spread than OKW but I don't consider it significant. These numbers show a pattern similar to that present in the OKW example. Here again the number of points needed for a particular villa appears linked proportionally to the size villa (square footage).
You get a lot less square footage at BWV for your point. The numbers are further exagerated by the size of the villas within each resort. For example the OKW GV is 68% larger than the OKW 2 bdrm. While the BWV GV is 100% larger than the BWV 2 bdrm.
If given the total number of points needed for the whole resort for a year and tasked with determining the points needed for each size villa within a particular resort my results would be very close to the current points chart.
The square foot per point calculation was based on the total number of points needed for one year in that particular villa at that particular resort. Square footage figures were obtained from this
thread. The number of points needed for one year at each villa was obtained from The DVC Planner by Caskbill (Thanks Bill).
