Hi
Marissa! Be sure to catch the early "Character Breakfast" complimentary bus from your
Disney Resort Hotel. That bus will have you arriving at the
Magic Kingdom turnstiles before your dining reservation at
The Crystal Palace. Look for the turnstile opened for early Advanced Dining Reservations (ADR). A Cast Member will be checking ADR Confirmation Numbers from guests wishing to access the theme park before official park opening hours. Be sure to bring your ADR Confirmation Number with you.
One advantage of getting to the theme park super early is that you will have access to a virtually empty Main Street U.S.A. That will give you the opportunity for some amazing pictures of Cinderella's Castle without crowds in the background. Your experience at The Crystal Palace will most likely last until 9:00 PM. However, should you leave the restaurant earlier than than, you can always go back to the park entrance and enjoy Rope Drop, the official daily park opening ceremonies.
Please let me know if I can be of any further assistance. Have a memorable vacation to the Walt Disney World Resort!
