The two times that we have done it, I did not receive a call from Concierge staff. I called them and emailed them. For some reason, the DVC reservation was not showing up. I called at the 180 day mark. It fills up fast. I know that when the 90 day dining started, we were scheduled for this stay. I called at the 180 and was told to call at 90 plus 10. Now that dining is back to 180 plus 10, I would call Concierge and find out what the booking window is.
