OK, let me try to help as much as I can...
First, the basic AP/AP voucher info.
1). Only WDW Guest Services will issue an active AP.
1). Whenever you pay for an AP anywhere other than at WDW you are issued a voucher. You then need to take that voucher to a Guest Services window where they will issue the actual AP
with that day's date. This is now your anniversary date.
2). In order to qualify for the renewal pricing, you must renew the pass within 30 days +/- of your current anniversary date. ***The passholder website now allows for renewal 60 days before or 30 days after.
3). If you process yor renwal on-line you will be mailed a voucher that you still need to take to Guest Services to get your actual pass. On a renewal, the anniversary date stays the same. Ex. Your anniversary is 8/22. You will be in the parks 10/1 so you renew online by 9/22 (otherwise you'd go past the +30 days). On 10/1 the new ticket you receive at Guest Services will still have an expiration date of 8/22.
Now, as for the 15 month promo:
Around this time last year (IIRC) WDW announced that, for a limited time, AP renewals
for existing passholders would be valid for 15 months instead of 12. The August 31 promo expiration was/is to ensure that everyone who had an AP at the time the promo was announced could qualify for the 15 months.
So, if you already renewed your pass this year you have already received the 15 months. For example, our previous anniversary date was August 15. We renewed our AP's in person on August 26, 2009. When we renewed, our anniversary dated changed to November 15, 2010. Now, the earlist I could renew again would be September 15 (60 days prior). They did this for a reason (IMO).
Now, I know there are conflicting reports as to whether you have to physically redeem a voucher in person by 8/31 or simply pay for the renewal. I trust Cheshire Figment's account that it must be done in person but I really don't understand why since the new anniversary date would be fixed (based on the original), regardless of when the voucher is redeemed.
We renewed ours in person shortly after the promo began so unfortunately I can't share a personal experience. Hopefully others will post who have personal experience not just going off what MS/CRO says.
Hope I didn't confuse things more
