My sympathies Kevin, that would be a tough pill to swallow. But, maybe you can use the time to wander the DIS boards more, get some great ideas and get a jump on some great ADR's for meals you want with certain characters etc... I have never used this, but there is a book about being the Unofficial Planning Guide to your WDW Vacation, or something like that. I know you can get it in the travel section at book stores. If you pick it up now you and your GF can use the time to plan. This can be so much fun!! I love to plan a trip!!!
On a side note, can I ask about the 40% off email you got? Where did it come from? Do you subscribe somewhere to get this sort of thing?
WHen you go, have a wonderful time!!!
