It's great to see you here today at the Disney Parks Moms Panel, Debra!
Since your question is time-sensitive, I'll get right down to it and tell you that buses will be running between
Disney's Port Orleans Resort - French Quarter and
Magic Kingdom Park tomorrow morning so you do not need to cancel your
Cinderella's Royal Table reservation. Your route there will likely be affected by some road closures for the
Walt Disney World Marathon so for that reason, I recommend leaving at least an hour in advance of your reservation to ensure that you have enough time if you encounter any delays because of the race. You also have the option of arranging for
Minnie Van Service to come and pick you up at your Resort Hotel and drop you off right in front of Magic Kingdom Park if you prefer a private ride. There will be a lane open for taxi and rideshare drop-offs at the Transportation and Ticket Center as well, so you can also head there and use the
monorail or
ferry to get to the entrance gate.
Since you're staying at a
Walt Disney World Resort Hotel, I also recommend that you chat with the
Lobby Concierge tonight and they'll be able to give you specific instructions for buses and other forms of transportation based on the most up-to-date information they have.
Have a magical day, Debra, and say hello to Cinderella for me!
