Hi Lesile!
Thanks for sending your question to the Disney Parks Moms Panel! In order to book your dining reservation for restaurants that require pre-payment, all you will have to do is enter your Magic Your Way Package Confirmation Number prior to booking your
Advanced Dining Reservations online. If you would rather call and speak to a cast member to make your Advanced Dining Reservations by calling (407) 939-3463, the Cast Member will ask for your confirmation number at the beginning of your conversation in order to link your Disney Dining Plan to your Advanced Dining Reservations.
With the Disney Dining Plan, you will not be required to pre-pay for these reservations, you will simply need to use your credit card to "hold" your reservation. If you do not attend your reservation, a cancellation fee will apply and be charged to that credit card.
If you have any other questions while planning your Walt Disney World Resort Vacation please don't hesitate to send me another question. I would love to help make your "Disney Time" even more magical.
Stephanie
