You might want to think about buying the AP now. Historically, prices will go up in August, which is getting close. You can buy the voucher on-line from anywhere in the US and it will be mailed to you. I have done this several times and it works well.
The good part is that the AP year does not begin until you exchange the voucher for a pass. So, if you get to the resort late, hang out at the pool, and then go to a park the next morning, that will be the first day of your "year." I have had no luck exchanging vouchers at the resort. You will need to go to guest services at either Downtown Disney or a Park Entrance to do that.
You can make an AP discount reservation with your voucher, or through an agent with the promise to procure an AP/voucher. You will need either the AP or the voucher when you check-in.
Something to keep in mind about AP discounts. They are not available too far in advance. In fact, they are usually only available 60 days before your trip, so it's not quite discount utopia. Think about
AAA Club discounts, too. For our upcoming trip (I belong to both AAA and have an AP) I chose to head to WDW for a quick one night trip on the tail end of a business trip just to get a Bounce Back Offer discount of around 45% on a Boardwalk Villa one-bedroom during Food and Wine. It was 8 months in advance. Usually when I try to get something that far out, with a discount the pickings are slim. Closer in, especially for Food and Wine, it is incredibly difficult to book an Epcot resort with any sort of discount.
