I was on the Disney wait list to add on at VGC late last year.
One Saturday I called MS to check something about an upcoming reservation, and the CM said, "Oh, you have XXX points available at VGC". I told her she was wrong because I had used all ny points for the reservation and nothing left.
Turns out she was right. My wait list had come through; the points had been added to my account; never even heard from my guide.
So, yes, they are very fast once they have your credit card info. So fast you might not even know you got more points!
