For what it's worth, I ran some numbers last night. Using the 2018 calendar as my basis (for determining number of days in each season, weekdays vs weekends), I applied both the 2019 and 2020 point values for BCV. Room counts used were 36 studios, 20 One Bedroom villas and 152 Two Bedroom.
@drusba previously indicated that lockoffs should be counted as 2Bs, which makes sense given that there is no guarantee owners will book them separately.
Summing all points required to book all villas for the full year, I came up with the following numbers:
All 2Bs counted as 2Bs
2019 chart: 3,027,324 points
2020 chart: 3,027,928 points
That's an increase of 604 points for the full year. Given that 2018 is probably not the Base Year used by
DVC and the variance is less than .02% on more than 3 million points, this is an acceptable variance. I performed the same analysis for SSR (much more complex with standard/pref views, treehouses, etc.) and ended up with a variance of +450 on more than 14 million points.
In this regard, I have no reason to question the validity of the charts. To the naked eye it looks like costs rose on far more rooms/views/seasons than where they declined. But the number of villas in each grouping, number of days in each season and exact amount of each +/- change all play a role in balancing the totals.
I then did a second comparison for BCV where I counted all of the lockoffs as their separate 1B + Studio components to evaluate the gap in points between booking lockoff units as one room vs. two rooms. In 2019, it costs 5 MORE points (42 vs 37) to book a weekday Adventure Studio AND One Bedroom vs booking that same physical room as a Two Bedroom villa. In 2020 that disparity will increase to +7 points.
Does that mean owners are collectively paying more for Studio + 1B bookings at BCV in 2020? The answer appears to be yes.
Assume for a moment that all lockoffs are booked separately as 1B + Studio. Changing my room counts to 110 Studios, 94 One Bedroom (both numbers including the lockoffs) and 78 Dedicated 2Bs, I came up with the following numbers:
Lockoffs counted separately as Studio+1B
2019 chart: 3,219,058 points
2020 chart: 3,282,118 points
That's an increase of 63,060 points over the course of the year or 1.96%.
At this particular resort, owners staying in lockoff Studio and One Bedroom villas will collectively pay more points in 2020 than in previous years.
However, with BCV this may be a phenomenon that falls under the heading of unintended consequences--or at least uncontrollable consequences. Remember that my initial set of numbers at the top of this post are the true basis for the
point chart. It's impossible to narrow that variance between Studio+1B vs 2B costs without impacting the overall total on the chart. Even minor changes create a ripple effect which alters the chart by thousands of points.
Consider the impact of reducing a 2020 weekday Adventure Studio from 16 points per night to 15. There are 36 dedicated Studios at BCV and 54 weeknights in Adventure season. That one point adjustment removes 1944 points from the chart. In the top set of numbers, instead of a +604 variance for 2020 there would be a -1340 variance. There may be other areas where a smaller adjustment is possible, but that wouldn't make much of a dent in the 62k gap in my "lockoffs counted separately" figure.
If most/all BCV lockoffs are booked separately, member points will be consumed at a slightly faster rate than in the past (~2%) which could lead to additional room inventory allocated to breakage, etc. That said, I don't see a clear path for DVC to narrow this gap while still accomplishing their (apparent) goal of raising Studio costs and tweaking other aspects of the charts. At least, not in the case of BCV.
Saratoga Springs is another matter. SSR has no dedicated Studio or 1B villas, so it seems as if those rates could be set at any reasonable level of DVC's choosing. Nevertheless, this gap between Studio+1b and Lockoff 2B pricing rose by 3.54% from 2019 to 2020. The collective cost of booking all of the lockoffs separately rose from 14.994 million points in 2019 to 15.526 million in 2020.
An Adventure season weekday standard Two Bedroom at SSR is priced at 28 points per night in 2020. That figure is material to balancing the points and I have no qualms with it. However, it's not clear to me why DVC assigned 12 PPN to a Studio and 24 PPN to a One Bedroom (total 36) in the same season. Members are paying 8 additional points every weeknight--for every lockoff--during that one season. I don't see any barriers that would prevent them from lowering either the Studio or 1B rate (or both) so that the combined cost is similar or equal to the cost of a lockoff Two Bedroom Villa. This variance has always existed at SSR (and most DVC resorts), but the gap is widening.
This disparity appears to be necessary at BCV and other resorts with dedicated Studio and One Bedroom villas. Perhaps DVC feels justified in applying a similar formula, even at resorts that only have lockoffs.
