[QUOTE=MomBee;1063706]so let me get this straight, ikf I have a 10 wpam and ph ticket then I can upgrade anytime within my 14 days to an AP? Do they just deduct the cost of the MYW ticket?So the price of Ap minus $370?[/QUOTE]Yes, but there is one complication. Your ticket has the Water park Fun & More option. If you have used ANY of the WPF&M admissions, then if you upgrade to an AP it must be a Premium Annual Pass (one that allows admissions to the water parks, etc.). If you’ve already used even one of those WPF&M admissions on your 10-day ticket, then you can’t upgrade that ticket to a “regular” AP, it would have to be a PAP.
But otherwise, yes, you upgrade your existing ticket to an AP, and you pay the price of the AP minus the price of the ticket you already own. The activation date of the AP will be the first day you used that ticket.
Think about it … Disney doesn’t penalize you for deciding you want an AP after-the-fact. And that’s why they back-date the activiation date of the Annual Pass … it’s as if you bought and activated the Annual Pass on the first day you used your ticket.
