I would do CP for breakfast as early as possible on an non-early entry day (so that I'm one of the first people in the park; great photo opps) and I would do CM for dinner.
Second that. There is never a better time to take pictures especially if you have little ones. We use to always do this when DD was younger. Plus you don't have to wait in the line for them to let you in! Even if you can't get ressies until 9 they want you there early anyway so they will let you in probably as early as 8:30 I would even try 8:15.
And I third that! We always try to get a first morning seating at Crystal Palace (8:05)... we love getting to walk down a practically empty Main Street and getting some pictures. Have a great time!
Crystal Palace for breakfast and Chef Mickey for dinner.
Get into the park for an early breakfast ADR, and then have a nice dinner at the end of the day away from the multitude at the park.
