Reservations for the Be Our Guest restaurant have officially opened today.  
Please call the dining line at 407-WDW-DINE or the general information lines (407-824-4321 or 407-939-4636) to make your reservation!
Reservations will only be available for the dinner period, as lunch meals will be available via a walk-up counter.  Reservations will also not be available on the 5th or 6th of December due to the grand opening events. 
Side note: Please make sure you give a credit card number if you do the automated system (be sure to eventually talk with an agent) as your reservation will be subject to cancellation if no credit card number is listed on file.  
Happy reservations!
