Hi Lisa! Welcome back to the Disney Parks Moms Panel! We LOVE helping guests just like you plan their family vacations!
Cinderella’s Royal Table in my opinion is a really fun breakfast! I love seeing all of the kids faces when the Princesses arrive! Having a dining reservation for before the park opens is a really cool experience! Walking down Main Street, U.S.A. and feeling like you have the place to yourselves is a magical feeling!
I would plan to arrive at Magic Kingdom Park no later than 7:45am. If you scroll through your dining reservation confirmation email, you will notice a little blurb about dining reservations for those that happen before park opening. It says “Guests with dining times prior to Park opening are required to provide the confirmation number to a Cast Member at the Park Entrance. Guests will then be directed to the restaurant location. Guests should allow 15 minutes walk time from the Main Entrance to the dining location.” In my opinion I think it is important to arrive at least 30 minutes before your reservation, since you have to check in with a Cast Member at the Park Entrance, and then walk to your dining location.
I hope that I have helped to answer your question! If you have any more questions please feel free to stop back anytime!
Say “Hi” to Cinderella for me!
