Keep trying!!! We didn't have any trouble getting ours at the 90 day mark, but when I last called to check on things, they had some of our party cancelled, couldn't find reservations, things like that. They had told my FIL it was sold out as well, he got his TA to call and they found room for him. Also, the cm I spoke to told me that you no longer have to wait until 90 days out, you can do it right when booking your rooms.
