I plan on purchasing AP when we arrive @ MCO. Can you purchase the DDE in advance without voucher? Also, what is the breakeven price with dining? We're not big foodies. However, we planned a TS every day. The AP is great for the room discounts that are currently offered. We are saving approx 1000.00 of room. But, not sure if the DDE is for us a family of four me, DH, DD11 and DS5. Any advice appreciated.
I posted a similar question yesterday on the budget board. I found out that you can upgrade your ticket(or buy your AP) the day you arrive, call the DDE phone number and give them your AP# and CC#, they will process your charge and issue a temporary DDE card for you to pick up the same day after 5:30pm. Hope that helps. You can check out the post over on the budget board too 

when you spend $300 in meals is when you would recoup the cost of buying it
