Welcome to planDisney Ashley!
Starting your day with a wonderful breakfast sounds fun! You can't go wrong with either
Chef Mickey's at Disney's Contemporary Resort or the
Grand Floridian Cafe at Disney's Grand Floridian Resort and Spa.
I do not know where you are staying, but with such an early reservation time, I suggest hiring an Uber. Lyft, or Taxi to drive you to your breakfast. This will give you door to door service, and much easier than buses this early in the morning.
After your magical breakfast at either location,
make your way over to the Magic Kingdom. From the Contemporary, hop on the monorail or walk over. The monorail will take about 20 minutes, and walking will take about 15 minutes from door to gate. From the Grand Floridian, the walk is about 15 minutes, or take the 5 minute monorail ride. All roads will lead to the front gate of the Magic Kingdom, no need to stop at the TTC.
Wherever you decide, make a
Dining Reservation as times do fill up, especially for that very popular time in the morning. Enjoy your day in the Magic Kingdom!
