MVMCP tickets for AP

Has anyone had luck using their AP discount for purchasing tickets for MVMCP the day of the party? Is so how much of a discount did you receive?

I haven’t tried on the day of – I bought my tickets ahead of time – but I was not impressed with the discount. If I remember correctly it was $2-3, less than 10% off. So even though I have an AP I chose the dates most convenient for me rather than the dates that offer AP discounts (not all party dates do offer AP discount.)
