When I changed my free dining ressie from 2 rooms at AKL to 1 deluxe room at BWI last week, I paid the small difference in cost during the call. I went online the next morning and it showed I still owed over $3K. When I called, the CM said the credit from the first room was applied, but the credit from the 2nd room had to go through another department and it is not lost, just waiting to be applied in the system. She said it can take up to a week for it to show online. I checked the next morning and the balance was zero. So it didn't take a week, only 2 days. I then remembered when I made a change from one resort to another a previous time the credit didn't immediately show up. I think your ressie is OK. I would call and ask for a supervisor to confirm.
