I'm not trstno1 but I figured I might help, if no one has answered your question yet.
I don't know if anyone has helped you yet with finding the website for Magical Express, but this is it.
put in disneysmagicalexpress.com, and that will send you to the right place. I would put in the exact link but I don't have enough posts up, according to what a rule said when I tried to post this with the exact link.
I had to call Disney to find out there was a separate website for this service, when I was trying to enter my flight info. You might want to mention you don't have your tags yet! Good luck.
