Hi Hope,
Thank you for visiting the Disney Parks Moms Panel with your question. I am happy to see that you are considering dining at Be Our Guest Restaurant, it is one of my family's favourite dining experiences at Walt Disney World Resort.
In order to dine at any restaurant located within a Theme Park, admission to that specific Theme Park is required. If you are not planning on visiting Magic Kingdom Park for the day, unfortunately your party will not be able to dine at Be Our Guest Restaurant.
With that being said, there are plenty of fantastic dining options located outside of the four Theme Parks at Walt Disney World Resort. Although the Beast won't be the host, my family loves dining at
California Grill at Disney's Contemporary Resort. This is a Signature Dining Location, and it provides wonderful views of Cinderella Castle as well as Happily Ever After Fireworks Showcase. For us, it gives us a little bit of Disney Magic while not actually being inside a Theme Park. Another option would be
Cinderella's Happily Ever After Dinner at 1900 Park Fare at Disney's Grand Floridian Resort & Spa. This buffet dinner includes character appearances such as Cinderella, Prince Charming, the Stepsisters and Lady Tremaine. The experience is hilarious and the food is delicious as well.
I hope that helps, Hope. Please let us know if you have any other questions we are always here to assist with your planning!
