Hello, Mary,
Thank you for sending your question to the Disney Parks Moms Panel. Since you are arriving November 30, 2017, you are already within your 180 day window, so you can begin making dining reservations now! You can make them
online or by calling (407) WDW-DINE. I do recommend starting by priority rather than chronologically and to always allow for some flexibility.
You will be visiting during a magical time with all of the
holiday decorations. In fact, you may want to try and set aside some time to visit some of the more popular resorts that are
known for their holiday decorations and perhaps even dine at some of them. I linked you to an article about holiday decorations at the resorts, and I'm also going to add
Disney's Wilderness Lodge is also incredibly festive!
Wishing you a magical trip! Please let us know if we can help with any further questions. -
Kara
