They do year-round theatrical entertainment for the entire family.  The shows are great, especially considering the ticket prices.  There's a core group of skilled adult actors who keep shows together, but kids as young as seven do some acting and dancing.  This isn't like a school performance, though.  It looks really professional.  I write this having seen their opening show of CATS, which was amazing.  I've also seen Sound of Music and Annie.  There are constantly new shows being scheduled.
