Hi Jessica!
Congratulations on your forthcoming trip to Walt Disney World Resort in June!
I have checked the
calendar for the days of your trip. Magic Kingdom theme park opens at 9.00 a.m. each day, except on June 21, when it opens for Extra Magic Hours at 8.00 a.m.
The buses typically start operating around an hour before the theme parks open, so unless you have your
Bibbidi Bobbidi Boutique reservation on June 21, the buses from Disney's Port Orleans Resort will begin operating at 8.00 a.m. I personally do not think the 8.00 a.m. bus would arrive at Magic Kingdom early enough for you to arrive on time for your appointment. If you could possibly consider changing your appointment to June 21, your bus would leave around 7.00 a.m., giving you enough time to comfortably arrive at Magic Kingdom.
If you have any more questions about this trip, please come back and ask me. I would be happy to help you plan your magical vacation!
