Mademoiselle Kari, it is with deepest pride and greatest pleasure that I welcome you to the Disney Parks Moms Panel! And now I invite you to relax, pull up a chair as I proudly present your answer.
Having a pre-park opening breakfast at Be Our Guest Restaurant is a fantastic way to start your day at Magic Kingdom Park. Once you have enjoyed your feast and the park opens, you will be right in the middle of the magic! I can certainly understand that you will not want to head all the way back to the park's entrance to
rent an Electric Conveyance Vehicle, or ECV. I am happy to let you know that there should be Cast Members stationed at the wheelchair and ECV rental shop upon your early arrival. There will be specially marked entrances for guests arriving for breakfast reservations, usually the far left Mickey touchpoints at Magic Kingdom Park. Kindly let the Cast Member know that you need to rent an ECV and you will be directed to the location at the far right. Be sure to give yourself plenty of time to complete your transaction, head down Main Street, U.S.A., and arrive at the Beast's Castle before your Advance Dining Reservation time.
Kari, I hope you have a pixie-dusted day! Please let us know if you have any other questions as you continue to plan your visit.
