Hey there, Lynette. Thanks for stopping by the Disney Parks Moms Panel with your question.
A breakfast reservation at
Be Our Guest Restaurant at
Magic Kingdom Park is a great reservation to have. It can be a hard one to snag. Dining reservations are not like
FastPass+ selections where you have an hour window to return. Your reservation time is your reservation time. However, I have shown up 10 to 15 minutes late before and have still been sat. Each
Walt Disney World restaurant actually has their own cancellation policy and handles no shows differently. If you know ahead of time that you won't be able to make your Be Our Guest Restaurant breakfast reservation, you can cancel up until 11:59 p.m. the day before without being charged. You can cancel your dining reservations online or by calling (407) WDW-DINE. Depending on what time your breakfast reservation is, you could always stop by the restaurant first thing in the morning and possibly push back your reservation time, depending on availability, to something that works out better for you.
I hope this helps, Lynette. If you have any other questions, please feel free to come back and ask. Enjoy your breakfast!
