It will be interesting to see if my Aug UYU 2018 banked points are eligible for the extension. They were originally for an early June reservation which also used 2019 points. I cancelled that reservation on March 30th so I could bank the 2019 points. (there had been no announcement about allowing late banking before my March 31st banking deadline)
I then (foolishly) used the 2018 banked points for a reservation in late July. After a few days I realized there was no way we would go in late July so I cancelled that reservation in early April. I was worried that if those points were last used for that late July reservation, even though I cancelled it in early April, they might not qualify for whatever exception
DVC might announce in the future. I therefore used all of my 2018 banked points to book a reservation in early May, which I knew would be, and was in fact cancelled due to the closure.
I wonder if DVC looks at the history of those points, and sees they were (for about 7 days) used for a reservation in late July, they will decide my points also do not qualify for the extension.
