Word of advice, don't cancel any ADR's until a week before you leave (or better the day before you eat there!).
Last year I booked CRT 2 days in a row & I got the 8:05 seating. I waited until the park hours came out & then I cancelled one of them about 2 months before I went.
Well guess what, Disney did a change of park hours. The MK was opening at 9 on Wed which was the day I kept & the MK was opening at 8 on Thurs which was the day I cancelled.
So guess what they changed? The MK was now opening at 8 on Wed & I was going to be eating breakfast. I was not happy.
