Every year for the last four I have worked for kidsfest (ie The Vancouver International Children's Festival). I run tent#2, the 550 seat theater later used by Bard on the Beach. If anyone wants to bring thier kids to see a show I can probably sneek you in, or at least get you a really good deal. Some of the shows have already sold out so you may be watching from the sound booth, but anything that has yet to sell out is fair game.
Email/PM me if you are interested.
