I will say it again...there is NO guarantee that there will be any discount codes for 2002. The only thing you can count on being available is a Disney Club rate or AP rates and even then it really depends on when you are going in terms of how many rooms they will let go at those rates.
This year, codes were an exception, not a rule. They came out anywhere from 2-6 months ahead of time. But again, you cannot count on them being available. Plan for what you can afford and then try for something better IF anything becomes available. Disney is out ot make money, not to make it easier for us all to get a good deal unfortunately. To expect anything more than DC or AP rates invites disappointement.
I am sorry if this is harsh or disappointing, but everyone needs to realize that the discount codes we have seen this year are not necessarily here to stay.
