I just spoke to a CM to make a payment on my ressie and she mention how great the bounceback program was ( my ressie was a boounceback from 1/09 trip) and I made a comment how I never get pins , so these are great for me. She then told me that I could call at anytime and have them check for a pin attached to my name/address. She then ofered to check for me and I had a $500 pin, but it was dates I couldn't use. I can't do Disney World 3 times in one year, 2 is my limit. Call and ask them to look, I still don't know why I have never received mine as my e-mail is current and all spam goes into a special folder I check.
Good Luck!
