I read somewhere, either on this thread or the MDE FAQ, about someone entering all of their info online to sign up for magical express, and then getting an error message, but still getting an email shortly after. That exact same thing just happened to me! I did find a link to sign up online (thanks to searching the DIS!), filled out all of the info, got to the last page and hit sbumit, and got
Page Not Found- 404 Error
The page you requested could not be found.
However, a few minutes later I got an email that started with Thanks for submitting your request for Disney's Magical Express, and had all of the info I entered in it. Do you think that means I'm signed up?
Dangit, I hate calling anywhere, and even I know that the way to straighten this up for sure is to just pick up the phone and call them. I could have just called in the time it took me to ask here, search the dis, fill out the form, and come back here again
. I was just so happy to have found a way to do it without having to call. FWIW, it also let me put my address in, instead of Citicard which is who I booked through.
