This is not a flame at Becobscot, who was posting personal, genuine experiences. No doubt that is what Disney said when called. Classic example of this board having more knowledge than some of the well meaning CM's (see my Wonder Trip report when I talk about the CM at check in).
Your observations are correct--DU's site has among its options, Disney Visa, which means....Disney Visa (from Bank One, which is being absorbed into Citi, I believe). Disney Card, in DU's site, means the Disney Rewards Card, onto which you can transfer your reward dollars earned on the Disney Visa program.
The entire two card system reeks of corporate bureaucracy and different departments fighting turf battles instead of coming up with one efficient system. To get points from a Disney Visa to a point where I can use them, as advertised, to pay for a
DCL cruise, I have to make two transfers, not one. I make them both online, minutes apart. They should have found a way to make it a one step process. And in the Mouse's defense, they were working with a vendor and probably most other large corporations don't have any less bureaucracy, just a little peeve.
Now enjoy those Disney Rewards Dollars at DU under the heading "Disney Card"!!
