The Candlelight Processional is an event held in Epcot every year in the American Gardens Theater. A celebrity narrates the Christmas story, in between carols and Christmas songs sung by a mass choir. It is truly a wonderful event. We saw it once and can't wait to see it again. For Christmas this year we're giving my parents tickets for the Candlelight Processional Dinner Package, similar to the Fantasmic Dinner package. You pre-pay your dinner, then get reserved seating at the theater for a specific performance.
I know there's more information on this site, I'm just not sure what to look for on the DIS Home Page. If you look at wdwig.com there is information there also.
