I just accessed the site with my exchange certificate, although it took a bit of fiddling with numbers -
I have 5 numbers on the far right of my plastic card - 12345 (not the real numbers, LOL!)
I have a date on there as well 01/02/03 (not the real date either)
Anyways, I typed in:
12301/02/0345 - see the code clue at the bottom of their login site (or did I type WTS:12301/02/0345 hmmmm)
Well, after two fiddlings I got admitted to the passholder site. I don't know why they don't make it easier for those of us who have already purchased the vouchers, but aren't going to activate them until we travel all the way to WDW to use them. If I'm only going to use them for our one long trip, what use is the info on the passholder site to me afterwards?
Sure, I know they want me to go down there and spend $$ another time this year, but why should I not be able to access the benefits (or at least get the info so I can use the benefits when I'm down there) beforehand? It's like paying for something, but not getting to use it until after the trip!
