I called the DLR AP line on Sunday and asked if they are using the DLR or WDW closure dates for the Premier Pass and the CM told me that she was only given the information pertaining to the DLR closure. I expect I will get a similar answer if I called WDW and asked the same question.
I think until Disney releases something specific to Premier Passholders we're going to be left in the information void.
Thanks for the update. I have not been able to call to ask. Guess it will continue to be a waiting game.
