I love pre-park opening breakfasts at CP, but last time we had a later breakfast there and it was nice to have a break after the first 3 hours of park touring. Towards the end of our meal, they were making the switch over to lunch as well, so if you time it right, you can get the menu of two meals rather than one. I also noticed a lot of guests cleared out during the switchover, and some of the characters came back around to play with kids or give extra hugs again. I prefer CP over CM, but if you can get a later breakfast at either, the timing can be better than during the meal rush times.
