Hi, Erik!
Welcome to the Disney Parks Moms Panel!
I'm so glad to hear that you're planning on spending one of your days at Magic Kingdom Park.
I'm not certain if you're planning on entering a Theme Park for your other mornings or not, so I'm going to give you a couple of recommendations for both. If you're looking to spend a morning in another theme Park, I would recommend Disney's Hollywood Studios. When my kiddos were little like yours, I found that sitting down for a Character meal was a great way to interact and take photos without having to wait in line.
Hollywood and Vine has Disney Junior Play 'n Dine with Characters from Disney Junior such as Doc McStuffins, Sofia the First, Jake and the Never Land Pirates and Handy Manny visiting! After breakfast, you could go over and watch Playhouse Disney - Live On Stage! where you'll see lots of Disney Junior friends!
We also really love having breakfast at
Cape May Cafe located just off the front lobby of Disney's Beach Club Resort. Beach Goofy and his friends are there to visit while you're enjoying a fabulous breakfast! The Characters are glad to sign their autographs too!
One more favorite is
1900 Park Fare located at Disney's Grand Floridian Resort and Spa. They've got a Supercalifragilistic breakfast with some amazing choices. Our favorite is their Strawberry Soup! You can meet Characters such as Mary Poppins, Alice in Wonderland, The Mad Hatter, Tigger and Winnie the Pooh.
I hope this helps, Erik! Let us know if we can help with any other questions!
Wishing you and your family a Pixie Dusted vacation!
