Hi
Matthew!
Congratulations on your upcoming visit to the Walt Disney World Resort! You will absolutely love breakfast with the Characters at
The Crystal Palace!
You don't happen to mention
when you'll be visiting, but you can purchase Disney Theme Park Tickets online and have them delivered to your home address. Online ticket purchases can also be picked up at the Will Call window. At least one Guest Services window will be open once you arrive. My Moms Panel friend Kathie offers some great insights about this
HERE.
Keep in mind that if you are staying at a Disney Resort Hotel your theme park admissions can be added to your Keys to the World (room keys), so you can use them to access the theme parks during Extra Magic Hours or for any early Advanced Dining Reservations.
During early entry, Main Street U.S.A. will be virtually empty so you'll have an amazing photo opportunity there before heading over to your breakfast reservation. Also don't miss your chance to take some family pictures in front of Cinderella's Castle without any crowds in the background. Please let me know if I can answer any other questions for you.
Enjoy a most magical visit to the Walt Disney World Resort!
