I took my family and in-laws to see "Cirque Dreams Jungle Fantasy" show at Northern Quest.
It was an energetic music/acrobats/light show that went non-stop for about a little over an hour. My kids were entertained and my in-laws thought it was nice. The costumes were elaborate and the soundtrack was broadway/dance hybrid that kept the action moving. One complaint is that the auditorium has a flat floor and sightlines deteriorated quickly from the front row on back. Luckily, it wasn't sold out and we could move around with the kids until we found seats where they could stand on the chairs without blocking anyone else's way.
I would probably do it again, for the kids especially. If you go, don't use Ticketswest. For my six tickets, it was $22 in fees. If you call the Northern Quest box office, no fees at all. I've learned my lesson.
