five days + 100 adolescents + seven chaperones + island paradise? = recipe for disaster. It's folly to think that we are so "enlightened" now that the old rules can be discarded with such abandon. The old rules were intended to preserve one's self-respect and, above all, one's safety. The old-timers were smart. As Bill Cosby would say, teenagers are brain-damaged, and they need a lot of supervision.
hell 2 teens with 7 chaperones is a recipe for disaster.
You just don't let people go into this type of situation when they are short of life experience AS WE ALL WHERE right after high school....
