Hi Yvonne! I love those Monsters, Inc. guys too; I have a picture on my desk of my four children with Sully and Mike. You can often catch these characters for a picture and a hug at the Backlot across from the Studio Catering Company in Disney's Hollywood Studios.
Breakfast with Lilo and Stitch at 'Ohana in Disney's Polynesian Resort would be perfect for your princesses. Hang with Stich while enjoying a family style breakfast of bacon, sausage, eggs, fruit, and more. Be sure to try the island-style fried potatoes.
My family loves the unique dining options at Disney's Hollywood Studios.The Sci-Fi Dine-In Theater and the 50's Prime Time Cafe both offer one of the most entertaining meals you will ever have. Watch ridiculous clips from old science fiction movies while sitting in a convertible car style table enjoying burgers and shakes at the Sci-Fi Dine-In Theater or step into a 1950s home for meatloaf and other comfort foods and catch a few old sitcoms at a formica topped table.
On our last trip to Walt Disney World, my family had a blast on the
Pirates and Pals Fireworks Voyage where fireworks were only part of the fun. Ice cream, cake, popcorn, and other goodies were served, Smee and Captain Hook came by, and then we boarded a boat for a water view of the Electrical Water Pageant and the Magic Kingdom fireworks.
If you would like more suggestions, just contact me with additional favorites of your daughters and some experiences you have already had so I can share events that will be new to you.
