The only ones that I know of are for the AP holders. Right now it is AP6 code - which starts prices for the DLH at $189 and I think $169 for PP? Not quite sure of amounts. We are paying $207 for upper floor, pool view at DLH in May. They didn't have a discount for GC.
Thanks for the information. It may be worth getting an AP. I go to DL once or twice a year. We went to WDW last Christmas for 7 days. It was wonderful! We stayed at the Poly and now I need to experience staying on property at DL, which I have never done. We usually stay with friends while we are in SoCal.
If you have a Disney Visa, they have a deal PP for $199/night or DLH (I don't know how much). If you do have a Disney Visa, go to their website and click on Disney offers to get to the deal.
