I was wondering about this myself And still not certain.
I
think it may be possible to use a second membership to get around that ‘one per membership’ but wouldn’t that extra membership would also need to be
DVC-Y?
I’m wondering about having a reservation booked on my DVC-N membership, is that eligible since I also have DVC-Y?
Doesn’t answer these questions but is interesting how some of it works-
