PP is right. But definitely keep checking. I had booked several ressies back at 180 days, but we JUST decided to move to a dining plan right before fd was open to the public.
In the past week I have gotten Chef Mickey at 7:05, Ohana Breakfast before 8:00, CP at 8:15, Fantasmic Package, and a bunch more. All at times I was looking for. I know my friend just got CRT twice. It's possible.
And as the trip gets closer things will continue to open up I think.
