I would suggest calling at the 180 day mark for any of the character meals. Chef Mickey's and the Princess breakfast in Norway are getting to be prized ADR's as well, depending on when you go. I always feel that it's safer to call at 180 and then cancel later if your plans change. Especially if you are not very flexible in terms of which day/which park or needing to eat at a certain hour due to medical or kid needs. Some of us can't get our kids to hold out for those later dining hours. On our first trip, we had a 7:45 at the Rose & Crown and DD(then 4) put her head down on the table halfway through dinner and fell asleep!
