It wasn't the best way to handle it, but last year, I managed to plan a trip, buy an AP and get the DDE in one week - not sent to my home, and it was an extra bit of hassle, chasing around etc. I ordered the AP ahead of time and arranged a will-call. Then I tried to get the DDE card, but I didn't have a voucher or AP number, so I called somewhere else (the DDE person directed me) to get my AP number in advance, and arranged to pick up both the temporary DDE card and the AP at Epcot the night of arrival. It was an extra hassle all around, but I got it pushed through! It would be much more pleasant to order your voucher a month or two out and use that to get your DDE card issued.
