I just made my 90 day ADRs for a group of 8 on Sunday. Once I finally got through to a CM, I had no problem getting ADRs for all the restaurants I wanted within an hour of my plans. I got ADRs for 8 at Le Cellier, 'Ohana, Crystal Palace, Biergarten, Mama Melrose (Fantasmic package), and Coral Reef. You should be fine if you call at 90 days.
