Hey there, Kathy. Thanks for stopping by the Disney Parks Moms Panel.
This is such a great question, I'd hate for you to be late for your breakfast. The
Crystal Palace is such a fantastic place to eat! If it were me, I'd leave
Disney's Pop Century Resort an hour to an hour and fifteen minutes before your dining reservation. The bus ride from Disney's Pop Century Resort to
Magic Kingdom Park is about 25 minutes give or take with traffic. Then you'll need to go through security, enter the park and then walk to The Crystal Palace which is pretty close to the front of the park. It also has a little spare time built in for those must have pictures in front of Cinderella Castle before you eat. I think leaving in that timeframe will get you to your reservation in plenty of time.
My favorite thing about breakfast at the Crystal Palace is the made-to-order omelet station. You can choose from toppings like bacon, sausage, ham, mushrooms, tomatoes, spinach, green peppers, onions, different cheeses and whole eggs or egg whites. Nothing says vacation to me like a freshly cooked omelet that I didn't have to prepare and these are really great!
I hope this helps plan your morning a little bit better. If you have any other questions, please feel free to come back and ask. Enjoy!
