Any time a code comes out to the GP, or Disney Visa or whatever...just call WDW reservations and have them check it against your reservation price...I had a code for this October and then the Disney Visa Code came out, of which I have a DV, anyway...I checked to see if I would save more with this new code and I would NOT have! It would have cost me $600+more...and then I knew that my first code was awesome! Justkeep checking with the DIS boards or mousesavers.com to see if new codes come out that will affect your ressie!
