Goofy4tink - boo! I'm having the same problem - bad 1st attempt, etc. I do not have an hour to spend on the phone with them!
I also have a bunch of user names because I had them send those to me (they send you a laundry list of every name you've ever used on any Disney site - so it includes ones my kids have set up, and me).
But I have used the same
DVC and Disney site passwords for years and never had a problem until yesterday.
GRRRR.
