We went last year. The date for booking your ressie is different from your ADR. Last year we could book ADRs at the 180 mark, but I had to wait until June to book CP. You may want to call and ask ahead of time if you can book the CP before the rest of your ADRs. Maybe with the 90 day change, they may not even release CPs until Sept?? Doesnt hurt to ask.
As for which dinner should you choose....I wish the post above me was around when I made my ressies. I chose Le Cellier, 5:30 for the 8:15 show. I was on the deluxe, so appetizers were included. We didnt get seated until 6:30. I also had breakfast that day at Tusker House and luch at Yak and Yeti. I wasnt even remotely hungry for Le Cellier, but could not resist getting in a biteful of the filet with mushroom sauce. When the breadsticks came my will power went out the door. I dont remember getting an appetizer (but I probably did!!) and ate the entire filet...it was that good! I skipped dessert, though the rest of my party didnt, so I had to wait for that, pay the bill and get out of the restaurant over the the stage for CP.
It was all I could do to keep from crying when I saw where I was and where I needed to be to get to the show. Im not sure if I made the best decision, but we opted for counterclockwise toward the UK. It was a LONG walk and on a VERY full stomach, it was not fun. We got there right when they were starting, needless to say, in the last row behind a tree.
If there is ever a "next time", I will skip lunch and choose burgers at the American pavilion for dinner!
