Greetings Julianne!
An early morning breakfast reservation at
Cinderella's Royal Table sounds positively enchanting. I do hope you have your camera and autograph book ready for the big day.
Getting to
Cinderella Castle will be easy and fun if you're staying at
Disney's Contemporary Resort. You may walk from your resort to Magic Kingdom Park. As you exit the hotel, just turn right, pass
Bay Lake Tower and follow the path to Magic Kingdom Park. Upon entering the theme park, you'll walk under the train station and then directly down Main Street U.S.A. on your way to breakfast.
If the weather is uncooperative that morning, you could choose instead to board the resort monorail on the fourth floor of Disney's Contemporary Resort and then you'll disembark at Magic Kingdom Park at the fourth stop.
Whichever route you choose, enjoy your meeting and meal with Cinderella!
Wishing you many magical memories,
Jill
