Hiya, Jessica!
It's so exciting to take little ones on their very first trip to
Walt Disney World. I remember how my girls reacted when they were the ages of your kids, and even though one of them was afraid of the characters, just about everything at Walt Disney World was magical to them.
You will have no trouble feeding rumbly tumblies at your resort,
Disney's All Star Movies Resort. The resort is home to the
World Premiere Food Court, which is a short walk from just about any room at the resort. The food court has five different food stations, plus some quick options, like cereal and milk or fruit and yogurt.
You're also welcome to venture out to any of the other resort hotels to grab a bite to eat at one of the restaurants or food courts. You'll want to take your resort transportation to any theme park, then use the transportation from the theme park to the resort where you want to eat. You'll find options that include character breakfast experiences, buffet breakfasts, and regular table service meals. This means you'll have to get up a little earlier if you want to eat before you head into the parks, but in some cases, it might be worth it.
There are also some great dining options inside the theme parks. Both restaurants and some kiosks will offer breakfast selections.
Have a great time on this first vacation for your family! I hope you make many magical memories.
Anna
