I am so frustrated with this process! I was in my late teens or early 20's when I originally signed up with Disney's website. I don't remember exactly when or what made me sign up. Since then I have moved several times, gotten married...and grown up a little. So I changed my email address and stopped using that old one. Mostly so I could have a 'normal' email for job hunting or business matters. I signed up my updated email and information at Disney website. I still check the old one occasionally. This year alone I have gotten 5 pin codes sent to that old email. Each time I call they wont let me use it because my last name is no longer the same and I cant remember the address on it. Honestly, I'm starting to wonder if I made up an address just to sign up. I just cant remember. Luckily a few months ago I found one understanding CM who let me book with the pincode just by verifying the email it was sent to when I explained the situation. She told me that they cant update information once its put into their system in the original form. That means no name changes or address changes?! What?! Do they not expect people to move...get married or get divorced? Unfortunately we had to cancel that trip I love receiving pin codes but its so frustrating to not be able to use them because I cant remember the address I put in 10 years ago.
