Took a bachelor party crew for a Saturday afternoon of bruises and serious welts.  They have 2 fields..one small, one big but big was the only way to go for 12 guys.  Staff was very helpful in explaining everything to novices.  They really stress the safety aspect of it which is great if you wanted to bring teens to a place like this.  Just make sure to wear a sweatshirt if you don't want your bruises to last a month and clothes you don't care about!!
