Your guess is as good as anyone elses

Codes or "pins" as they are usually called are either mailed to you or sent in an email. Why you get one is a mystery. It is believed you have a better chance by signing up on the disneyworld website...getting your email and mailing address in their database, even applying for a disney visa card. I have done both, even joined the disney movie club and bought things at the online
disney store and still no pin

So I guess who knows. Now there are some deals that are available to different groups of people, annual pass, florida residents, disney visa, and general public that offer codes. Right now there is a code for room rate reductions for select dates up to dec. 24. It is not available to the general public YET but will probably be opened up in a few days for them.
