Ratpack-
I just asked for the Disney Visa room discount. I have not yet received my Visa statement this month, so I don't know if they will be posted in there or not. She let me know the rate and I was about to change my reservations from AP to the Visa rate (it was the same for the CBR for my dates of travel). I did not realize that the rate was only FL residents. While I was on hold, I saw a post on this board where someone mentioned that if was only for FL residents. When she came back and told me that my reservations had been switched, I asked and she verified that yes it was a FL resident rate. Since I'm not a FL resident, I left my reservations as is using the AP rate.
To answer your question, the rate I was quoted was $617 for 7 nights for CBR. I did not need a code.
