Adrenaline does have Friday evening bonus classes 5-8pm.  The email from Adrenaline says ages 12 and up and intermediate to advanced level.  In previous years, the classes were geared towards the older ages.   They were primarily contemporary oriented & some were improv based.  If your child is 12 and wants to try, and knows the above info, go for it.  It may be challenging for some 12 year olds and then again, they may love being that challenged at a convention !
