We did the breakfast on Friday, 4/6. It was me, DD17, my sister, her DH, and their two kids -- boy 9 (it was his true blue birthday) and girl 7 (her birthday was in January, but we were celebrating both birthdays).
The characters were Goofy, Donald, and Minnie. We had a 10:50 ADR. The characters came by twice each. They were nicely spaced and had good interaction with the kids. The food was quite good. It is a buffet and has the usual breakfast foods -- scrambled eggs, sausage, bacon, frittata, Mickey waffles, etc. The french toast bread pudding was tasty!
Our server, Caroline, was terrific. She kept our beverages full and was very attentive. She brought out birthday cupcakes for the kids when Goofy came around the second time. Our section of the restaurant sang happy birthday and it was very special. Caroline also gave the children cards that had the three characters' signatures and she also had Birthday buttons for them.
We've done most of the character meals at WDW and we were very happy with the Cape May Breakfast buffet.
