How far in advance do I need to order it. I am going July 16-31.
The DDE expires at the end of the month in which you order it plus one year. So if you order it today, it will expire April 30, 2006. Because of delays in shipping out the cards, they are adding a month or two to the expiration date so in fact your card would probably expire June 30, 2006. But my point is that the clock starts when you ORDER it, not when you first use it. So the longer you wait to order it, the later the expiration date.
If you don't mind using the confirmation letter instead of having the actual plastic card, order it about 2 weeks before your trip which would allow plenty of time for your hardcopy letter to arrive in the mail. The hardcopy letter has an expiration date, too, generally at the end of the month after the month in which you order the DDE. So if you order the DDE today, your letter will probably expire June 30, 2005.
If you absolutely must have the plastic card for some reason (and I can't imagine what that reason would be) then order at least 8 weeks in advance. The worst case is if you try to time it so you get the plastic cards but fall just short. What happens in that case is your hardcopy letter will have expired and won't be useable and you don't have the plastic card yet so you'll have to call the DDE office again, get them to generate a new letter with a new expiration date and then go to Epcot to pick it up. You probably want to avoid that scenario!
If you think you might visit WDW again about 12-13 months after your July trip, then the later your order the DDE, the more likely it is that your membership will still be valid on your second trip.
