Jerry, we love guests who ask us questions!
The Candlelight Processional is a spectacular presentation of the nativity story. A celebrity narrator- last year I saw Neil Patrick Harris!-, an astounding orchestra, and a choir of hundreds make for a dramatic evening. Be prepared to be full of the Christmas spirit after you experience this event. A dining package provides you guaranteed seating which is a wonderful thing considering how long some guests wait in line to snag a seat.
Candlelight Dining Packages do require two Disney Dining Plan credits for lunch or dinner at any participating restaurant. In
2012 Magic Your Way Package Plus Dining under Disney Dining Plan there is a section of special dining experiences available and the number of dining entitlements needed. Events that require two credits, such as Cinderella's Royal Table, Disney dinner shows, and Candlelight Dining Packages, are listed. Of course this information is easy to forget by the time you make your dining reservations.
Wishing you a fabulous holiday evening of beautiful music and good food.
