Hi Kenneth,
Thank you for sending your question to the Disney Parks Moms Panel.
Be Our Guest Restaurant is a very popular Dining Location at Magic Kingdom Park, and even after several years since opening, can still be difficult to secure an Advanced Dining Reservation.
Currently, Be Our Guest Restaurant is a Quick-Service Dining Location for Breakfast and Lunch Reservation and a Table Service Dining Location for Dinner Reservations. I have not been able to find any information stating that Be Our Guest Restaurant will eventually becoming a Signature Dining Location. Disney has not given any hints to support that rumor, so for now it is just that, a rumor. I would suggest keeping an eye on the
Disney Parks Blog as any major changes or announcements will be announced there first.
I hope that helps to ease your fears, Kenneth. Please let us know if you have any other questions, we are always happy to help.
Stephanie
