Hi Peter!
Thanks for stopping by the Disney Parks Moms Panel. I am so happy that you are planning on enjoying a Character Dining breakfast as it's one of my family's favorite ways to start a magical day! Generally,
complimentary resort transportation buses start 45 minutes before the theme park opens. However, I have often found that buses often begin earlier to accommodate Guests with early breakfast reservations. I recommend that you call the front desk at Disney's All-Star Music Resort the day before your breakfast to get the bus schedule to Magic Kingdom for the next morning to determine if the buses will be running early enough for your reservation. The second portion of your trip will be using the
Resort Monorail to get from Magic Kingdom to Disney's Grand Floridian Resort & Spa. The Resort Monorail system begins running 30 minutes prior to theme park opening, which may not be early enough depending on the opening time of Magic Kingdom.
If transportation isn't running early enough to get you to your reservation on time, I recommend that you consider using the
Minnie Van Service for transportation to Disney's Grand Floridian Resort & Spa for your breakfast. This service utilizes the Lyft app to provide you direct, personalized transportation throughout Walt Disney World Resort at a fixed price. I love to use this method of transportation for morning reservations because I have found it to be much quicker than using the buses, so I get a few extra minutes of sleep before a big theme park day!
Please let us know if you have any other questions as you continue planning your trip. T-T-F-N, ta ta for now!
