Boy, this will be all of them, yes planing on the dining plan
Character Meals are overpriced so the best time to do them is on the
DDP, so that is good. As the kids get older you can cut back on them.
You have repeated the same characters in a few.
Chef Mickey, Mickey, Minnie, Goofy, Pluto, and Donald. My LEAST favorite for food, characters, noise, cleanliness. With meeting many of the same characters I would change this to something else. Not sure where you will be that day but I would consider Crystal Palace with Pooh & friends OR 1900 Park Fare as both breakfast and lunch are fun and good for boys or girls.
O'hana, guessing breakfast so Lilo, Stitch, Pluto, Mickey. This gives you some variety and be waited on.
Garden Grill, one of our favorites, great boys, Mickey in farmer clothes, Chip, Dale
Hollywood and Vine-lunch, never done but the lunch characters sound perfect for the age
Cape May-breakfast, love the characters outfits Minnie, Goofy, Donald and enjoy the buffet
