I think a retail mistake and a room mistake are far different, I honestly didn't even see the discount listed on the main page I just went straight to my account to change my reservation and it showed up. I have a couple of times in the last year gotten AP discount rates above what was listed, like an AKL for 40% this summer making it cheaper than a moderate, and a YC last October for 41% taking it down below $300. The discount both times was listed for lower than 40% so I generally just book stuff when I see it at a good rate.
I am going to give it until next week or until I see they have "fixed" the issue and see what happens. I may call up later next week to pay the rest of it and see what my total is. If it's the same as what is listed in my receipt email I won't worry unless Disney contacts me. I also didn't get a 60% discount, mine wasn't that high, it was high but still well enough below 60%. I know there are a few people that got it at that low, but I wasn't THAT lucky. I am just going to play the wait and see, there is still tons of availability in rooms at BWI so I'm sure once they do sort this all out I'll have more options than I did this morning if I do need to modify. Who knows, I may keep the room at whatever rate they land on, but I'm keeping my fingers crossed they'll let me keep it (it's only a 3 night trip, not like I'm staying for a week).
