Welcome, Alyssa!
Thanks for bringing your great question to the Disney Parks Moms Panel. Celebrating Thanksgiving at the Happiest Place on Earth with your family sounds practically perfect in every way.
All
dining reservations at the Disneyland Resort can be made up to 60 days in advance online, on the Disneyland app, or by calling (714) 781-3463. In the past, special Thanksgiving menus have been available at Table Service restaurants throughout both parks and Disneyland Resort Hotels. You'll be able to find traditional favorites that feel just like home but topped with some Disney magic! Since this is a popular time to visit these restaurants, I would make sure you mark your calendar and set your alarm to make your holiday reservation as soon as you are able. While special menus may not be released until closer to the holiday, it wouldn't hurt to call Disneyland Dining before your 60 day window to see if any holiday meal information is available. Also I suggest keeping your eyes on the
Disney Parks Blog in the next couple of months for more Turkey Day details.
Since you are staying at Disney's Grand Californian Hotel & Spa, I hope you are able to take time to explore the details and amenities of this stunning hotel. The breathtaking lobby, fantastic dining, and pools make this my absolute favorite Disneyland Resort Hotel.
I hope this helps, and please return if you need any more help planning your magical vacation!
