Bonjour Jennifer. Thanks for your question.
Glad to know you have an early breakfast reservation for
Be Our Guest Restaurant. An adorable place, with delicious food. Absolutely a magical way to start off your day at the Magic Kingdom Park.
You will be able to enter the park even if your reservation is earlier then official park opening. There is usually one special entrance for those with reservations. There is a sign and a Cast Member nearby to assist you. Make sure you have your dining reservation number and a valid park admission ticket. It usually takes my family 20 minutes of walking from Magic Kingdom Park entrance to Be Our Guest Restaurant. We love taking pictures of the park almost empty while walking, especially in front of Cinderella Castle.
If you are taking a taxi to Magic Kingdom Park, remember there is no auto traffic directly to Magic Kingdom Park, they will drop you off at Ticket and Transportation Center. Another alternative would be to ask the taxi driver to drop you off at
Disney’s Contemporary Resort, and you can walk to the park from there.
Don’t hesitate to come back if you have further questions.
Have a wonderful day!
Gina V.
