Hello there Louanne!
Your daughters' first Disney trip is fast approaching! I'm so excited for you! It looks like you have it covered when it comes to dining! Are the Character Breakfasts you are planning to attend on different days? If they are, you may want to plan each day out ahead of time to see where all of the character meet and greet locations are in the parks. When you arrive at the parks, make sure to read the park's times guide to know when certain characters will be making their appearances.
With the girls being at the perfect age, you may want to take advantage of
Disney's Photopass Service to get all of your photographs throughout the parks and at your character breakfasts. I've been to various character meals and the photos can get rather pricey. With an upgrade to
Photopass+ the pictures are included in the price and also the ride photographs at certain rides around Walt Disney World.
And finally, if you are going to be going to Disney's Animal Kingdom, the park typically closes earlier than the other parks. If I have watched all the shows I wanted to watch and ridden all of the rides I have wanted to ride, I like to leave right after
Mickey's Jammin' Jungle Parade and head over to a park which is open later. That way I take advantage of the Park Hopper feature.
Let me know if you have more questions! We are always here to help you! Have a wonderful day!
