DVC Discount - P&P Party

[donmil723]

We can't decide if we want to go to the P&P Party on Monday, 2/5, since it is supposed to be pretty chilly that evening. I'm thinking I need to decide by Saturday at the latest since DVC members get a discount on that date for tickets purchased in advance and Saturday will be the last time MS is open before the day of the party. Or does anyone know if can I order them on Sunday, 2/4 at VWL after we arrive and still get the DVC discount?

Thanks!
