Another way to look at it is from the view of comparing current apples to apples to see how much of an initial impact there is when both price and points per night are considered. Assume you are a new purchaser and would like to get a week in a studio annually during Magic Season (what you need to buy if you have any school aged kids). You look at resale for BWV and see that you can get the best view on site, boardwalk view, for 132 points during magic season. At $80 a point resale, it will cost you $10,560. Now suppose Poly comes in at $160 a point and the same points as VGF. A lake view will be 199 points per night for a week in a studio in magic season. At a $160 a point, it will cost you $31,840, three times more than BWV. In fact, you can get a 2BR boardwalk view for a week in magic season at $80 a point for $28,000, three thousand less than that studio with an inferior view at Poly. In fact, even if you are a rich sheikh, you can get three BWV grand villas for a week during magic season for about the price it will cost you for one week in one of those significantly smaller 2BR bungalows at Poly if, as expected, the points are the same as the VGF GV.
And now you really need to think about another issue. With 360 studios there is a very good chance that Poly will be available at 7 months out many times of the year, particularly between mid-Jan and mid-Sep, DVC's slow to moderate demand season. If that assumption is correct, your real value lies in buying SSR in resale to get those 199 points needed for a Poly lake view studio during magic season.
Completely agree with this
last point-- your best bet is to get SSR (which is the best value)
unless you
need to book one of the very few room types that sell out before 7 mos.: AUL standard views, AKV value/concierge, BCV two queen 2bdrm, BLT standard views, VGF studios/2bdrm lock-offs, BWV studios/2-bdrm lock-offs. Given
PVB should have the same overall point rates as VGF, I'd expect that to put a damper on demand, at least for Bungalows. However, VGF studios regularly sell out before 7 mos. despite their higher point price compared to other WDW resorts, so same could hold true for PVB, esp. initially.
As far as your first point, it's a valid consideration, but while you will save money up front you will still spend more per individual point used over time. Best example of where you fall into this value trap is VB, which has the lowest face value ($40 CPP) but
highest actual cost per individual point used ($10), so why while you will save money up front you'll spend more over time. That said, if it's all you can afford, then understandably it's still a valid consideration. Conversely,
if you can afford it PVB is a decent value on a total cost per point basis, given you are buying more points with the contract -- and this value is limited since the price will go up and points will go down over time, so if you are going to buy, you should buy now. You can always wait and buy resale, but typically the resale values are proportional to the initial offering price minus used points (e.g. $145 VGF presale price x 48/50 years = $139, which is what VGF resale is going for currently).
)
But I'm guessing they'll do a lakeview studio for somewhere in the 160 range and perhaps a standard in the 130 although I'm kind of thinking I'm low on that number. And that then compares to 107 points for a VWL studio that now also sleeps 5.
