Hi Jessica,
Hooray for getting a lunch reservation at Be Our Guest Restaurant! That's one of the most popular spots to dine at Walt Disney World these days, and for good reason. If you've dined in Beast's Castle before, then you know that the food is delicious and the setting is absolutely breathtaking.
I'm happy to say that you will still have the option to pre-order your lunch by having that reservation. You can do that (or make changes to your order) anywhere from 30 days before your reservation date up until 5 minutes before your reservation time. To place your pre-order, go to the
My Reservations and Tickets section of
My Disney Experience. When you log into the site, you should see your Be Our Guest Restaurant reservation information on that page, with the earliest date you can place your order listed on the right side (under the Confirmation Number and above the Cancel Reservation link). I'm guessing your magical day will be here any day now, based on your arrival date, so once that happens you'll see a link there that you can then use to pre-order your meal. Based on my own experience dining here for lunch, I wouldn't expect it to take more than an hour.
Don't forget to order one of the delicious cupcakes for dessert, Jessica! Bon appetit and have a pixie-dusted visit!
Beth
