Hi Breck!
It is a pleasure to help!
The Candlelight Processional takes place in the American Gardens Theatre, in Epcot's World Showcase, located next to the American Adventure. The Liberty Inn is located at the American Adventure, so this is the nearest quick service restaurant. As you enter Epcot theme park, remember to pick up a Park Map so you can see the World Showcase layout.
Other quick service restaurants that are nearby are:
Katsura Grill (Japan)
Tangierine Cafe (Morocco)
Sommerfest (Germany)
Boulangerie Pattisserie (France)
As December 22nd is during one of the busiest times of the year at Walt Disney World Resort, I would recommend you prepare to stand in line as early as possible for any of the showtimes. Have you considered a Candlelight Dining Package? -
see full details here. This allows you to book dinner or lunch at a choice of restaurants, and you will receive VIP viewing for IllumiNations: Reflections of Earth and guaranteed seating at the Candlelight Processional. This must be booked as a package by calling (407) 939 3463, or
online.
If you have any other questions, please come back and ask me.
