Hello, Michael, and thanks for bringing your question to the Disney Parks Moms Panel.
Walt Disney World Resort typically publishes
Park Hours (including Extra Magic Hours) 180 days in advance. While you can book your dining reservations 180 days plus 10 from your check-in date as a Guest at an official
Walt Disney World Resort hotel, Park Hours will only be released one day at a time.
My suggestion would be to book those hard-to-get reservations at places like
Be Our Guest Restaurant and
Cinderella's Royal Table at Magic Kingdom Park as soon as you can. Depending on availability, dining reservations can be modified later--but you'll want to pay attention to each restaurant's cancelation policy should you need to cancel a reservation close to its date. Keep in mind that Park Hours are always subject to change without notice, so although I agree that it's helpful to know the potential
Extra Magic Hours, I'd make those initial plans without that information.
Should you need to modify or cancel an existing reservation, you can use your My Disney Experience account online or the
My Disney Experience mobile app. The app is also great for
Mobile Food & Beverage Ordering at select Quick Service locations, too.
Best of luck to you, Michael! I hope you have a magical vacation.
Amy
