Minnie's Halloween Dine 2018

I will be going to Disney World in the Fall. I usually do the Fantasmic Dining Package. I want to do Minnie’s Halloween Dine this year. If I book the Fantasmic Package at Hollywood and Vine am I automatically booked for the Halloween Dine or do I have to reserve it a certain way to take advantage of both?

The Halloween part just refers to the costumes the characters wear, you’re fine.

Thank you!
