I just read on Mousesavers that the codes for Dec. probably won't be out til early Aug. We are going Dec 9-16. If we go ahead and book now with AAA, and then codes come out that could get us a better rate and better resort, can we cancel thru AAA and rebook without a penalty...even change resorts? Can AAA get us the same codes and book our trip for us, or if you go with codes, is it better to just do it all yourself? Thanks!
