It is VERY long, so keep that in mind. There are moments in which they engage children in the audience and invite them to come to the front for dancing and such, so your kids may get a kick out of that. The storyline of being true to oneself is slow-moving and may bore them, but they'd surely be wowed by the fire twirler.
In my honest opinion, though, it's an overpriced, overlong, overly boring waste of time with mediocre food and sloppy service. An absolute 'never again!' for us.
