I think maybe you don't understand how it works or don't grasp what's coming.
These owners largely weren't staying at the resorts which are closing, although certainly some were. But they were booking at other resorts at some point after the 10 month mark passes.
They will now have the ability to book those locations at 13 months instead of < 10 months. There will be pressure on high demand dates.
Look at it like this, most of us were fighting for a finite number of spots at high demand resorts for prime dates (Christmas, Thanksgiving, New Years, etc) at exactly the 10 month mark. That inventory we were expecting to be there at 10 months to the day, is going to be booked up by new access owners at some point before the 10 month mark even hits.
Those owners don't have to stay up at midnight at the 10 month mark, they can book 12 months and 3 weeks out.
Watch, its gonna happen.
