Hi, Karla! Thanks for stopping by the Disney Parks Moms Panel with your question.
Breakfast at Be Our Guest Restaurant is a great way to start your day at Magic Kingdom Park. My family is planning to dine there in a few weeks, and the Open-Faced Bacon and Egg Sandwich has my name written all over it!
You will definitely have plenty of time to make your 8:30 a.m. Advance Dining Reservation by using Disney bus transportation. The regular bus hours are listed as beginning one hour prior to park opening. However, Disney does realize that Guests need earlier transportation to the many bright and early breakfast meals offered at the parks. In my experience, I have hopped on one of these buses at our Resort hotel as early as 6:45 a.m. In your case, I would be at the Magic Kingdom bus stop at Disney's Pop Century Resort around 7:15 a.m. This will give you plenty of time for the drive over, complete admission to the park, and take lots of pictures in front of Cinderella Castle with your family. When you arrive at the park, just head to the far left Mickey touchpoint, which should be marked as a point of admission for those with breakfast reservations. Be sure to have your confirmation number handy, just in case.
I hope you have a wonderful day at Magic Kingdom, Karla. Pop by again if you think of any other questions as you continue to plan your trip.
