I just called this am and made my MVMCM PS for LTT and I when told the CM on the phone that I hadn't yet bought my party tickets and that we were staying at BWV he asked if we were
DVC members. When I said "yes" he said I should be sure to mention that when I call for the party tickets because there is a DVC discount -- although he didn't say how much! Since the AP discount is only for certain nights I guess that will make some people's decision on which discount to use for them.
