Hi Anna, and welcome to the Disney Parks Moms Panel with such a great question!
Having an early breakfast inside a Theme Park is one of my favorite things to do at the Walt Disney World Resort, and I am happy to tell you that you can enter the Theme Parks
as long as you have a reservation.
The
Be Our Guest Restaurant is my favorite place to start a day at Magic Kingdom Park, whereas
Tusker House is my choice to begin my adventure at Disney's Animal Kingdom Theme Park.
Magical Tip: One of my favorite things to do when I enter the Theme Parks early is to have my photos taken by the
Disney PhotoPass photographers and add them to my Memory Maker - the Theme Parks are usually emptier in the morning and you can grab great pictures by Cinderella's Castle with your group.
Please come back to the Disney Parks Moms Panel if you need any help or advice to make your next Walt Disney World Vacation even more wonderful. We love to help!
May the magic be with you!
Julie
