Hi, Virginia, and welcome to the Disney Parks Moms Panel!
As a Walt Disney World Resort hotel Guest you can
book your dining experiences for up to 10 days after your initial Check-In date at the 180-day mark, but you will only be able to see Park Hours 180 days in advance. My suggestion would be to make sure you go ahead and grab those hard-to-get spots as soon as possible. These might include Cinderella's Royal Table or Be Our Guest Restaurant in Magic Kingdom Park, California Grill at Disney's Contemporary Resort, or the all-new Storybook Dining at Artist Point with Snow White at Disney's Wilderness Lodge.
Since
Park Hours and Extra Magic Hours are always subject to change, it's best to go ahead and book those spots as soon as the opportunity is available. For those early morning or late night dining options, the restaurants' availability during those times will give you some indication of the Parks' hours, but I know you probably want to coordinate your reservations with early morning or late night Extra Magic Hours, too. Unfortunately you'll need to book those one day at a time from the 180-day mark to see how you can best maximize them in conjunction with Extra Magic Hours.
If you book a dining reservation and change your mind once the Park Hours and Extra Magic Hours are published, you can always cancel or try to modify your reservation using My Disney Experience online or through the mobile app. Just remember that cancellation policies vary from restaurant to restaurant, so make sure you check out the policy for each restaurant before canceling.
Hopefully, these tips will help you book your most magical dining experiences with ease! As you get closer to your vacation date, please let us know if there's anything else we can do to help you plan.
