Hello, Jacqueline! Thanks for stopping by the Disney Parks Moms Panel with your question!
I am so excited that you will soon be visiting the Disneyland Resort and staying at
Disney's Grand Californian Hotel and Spa! You will absolutely love being so close to the parks and the hotel itself is gorgeous beyond belief. Your voucher for premium
character dining can be used at Goofy’s Kitchen in the Disneyland Hotel (breakfast or dinner), Surf’s Up! Breakfast with Mickey & Friends at Disney's Paradise Pier Hotel, and Ariel's Grotto (breakfast or lunch) in Disney California Adventure Park until January 7, 2018.
I suggest making advanced reservations for whichever meal you choose as these restaurants are quite popular. Reservations can be made online or by calling (714) 781-3463 up to 60 days in advance. When you show up for your meal, let your server know that you have premium character dining vouchers as tax and gratuity are included. The only thing that's not included are alcoholic beverages.
I hope this helps! Have a fabulous time at the Happiest Place on Earth!
-Linda M.
