I completely disagree with the poster who said no to this question. If your kids enjoy music (familiar Christmas music), they'll enjoy the story and the show. It's not even that long of a show - probably an hour or less. It's far from a church service. The Voices of Liberty are elite singers and lead most of the show. Well known narrators tell the story. It's inspiring for adults and kids, at least those families who wish to hear the story of Christ. My kids loved it when they were young, and still do now that they're adults.
I would think it varies by kid. I kind of think of it like a midnight mass/Christmas Eve service. I was a stereotypical kid who thought church was boring and complained every Sunday growing up, but I LOVED the Christmas Eve service. It was “special” since it was at night and seemed so celebratory, and I loved hearing the Christmas story and getting to sing my favorite Christmas hymns. I absolutely would have loved this as a kid. But some of my friends still found church on Christmas Eve boring lol, and I don’t know if they would have been into this as kids either. Candlelight Processional has a lot of narration, and these aren’t really stars young kids recognize and get excited about. But it could be entertaining for those who like Christmas Eve service. It’s a similar vibe. It’s also longer than most Disney shows, so even kids who enjoy this type of thing could get restless halfway through. It’s really what are your kids into?
