Hi Lisa, You've chosen 2 of our family's "must do" meals so far! I think you will really enjoy both of those.
I have two other suggestions for you based on your itinerary.
If your boys are fans of Playhouse Disney, then they would enjoy the breakfast or lunch at "Playhouse Disney's Play 'n Dine at Hollywood Studios. See:
HERE. They would see characters such as JoJo and Goliath from
JoJo's Circus, and June and Leo from
Disney's Little Einsteins.
Another suggestion would be Donald's Safari Breakfast at the Animal Kingdom Park. While characters are subject to change, you will generally see Donald, Daisy, Goofy and Mickey. Those may be some of the same ones you will see at Chef Mickey's though, so you'll have to decide if you want to see some "repeats". We always like starting our Animal Kingdom day off at Donald's, and the characters are always so cute in their safari clothes.
Hope this helps and that you enjoy your magical vacation!
