I didn't read all the posts to this thread, but there is already a PIN code offer for 2008 :
Save 30%** off the nondiscounted price for stays most nights 10/21-11/3/07, 11/11-11/17/07, 12/9-12/15/07, 1/6-2/2/08, 2/24-3/1/08, 3/30-4/12/08, 8/10-9/27/08, 10/19-11/1/08, 11/9-11/15/08 and 12/7-12/13/08.
**The number of rooms available for this discount is limited. Minimum length of stay requirements may apply for Friday and Saturday arrivals. Additional per-adult charges apply if more than two adults per room. No group rates or other discounts apply. Advance reservations required.
This is not a general public code, so it is only if it was sent you via email, however I spoke with a GG CM today and she said they do often come out to the public a month or so later, althought they are usually not as good as the original pin code, it is a discount. Also for the past few years the Disney Visa code that comes out in August has been good in Dec, and that is what I use for late november to mid dec travel... and the CM said the Disney visa is usually one of the best codes (aside from
free dining).
