Something I learned from these is that Disney cannot sell more points than there is availability at the resort.
That seems obvious, but what it means in practice is that Disney has to undersell any resorts with lockoffs. For example, if every room at Saratoga Springs, which has no dedicated Studios or 1 BRs, is booked as a 2BR, Treehouse, or Grand Villa, it uses 14,041,340 points. Accordingly, Disney's report for Saratoga Springs indicates sales/owned by DVD of 14,031,570 points - basically spot on.
But If they sell the 432 lockoff units as Studios and 1BRs - and I bet that's what happens 95% of the time or more, that consumes 15,006,236 points. Or said differently, if no one was allowed to trade in or out of SSR, and all the lockoffs were booked separately, 6.5% of the rooms would be vacant because of the lock off penalty.
What is Disney doing with those extra rooms?
(LOL they're obviously selling them for cash stays which is why there is always availability 6 months out)
I checked Beach Club and OKW and the pattern was similar.
