I've only encountered this behavior on one of my cruises and it involved a husband finding his drunk wife in the cabin and company of another male guest.
I called security around 2am during a very violent altercation outside my cabin and within minutes the altercation was broken up and the offending parties were taken away.
I'm sorry that security doesn't seem to have been as strict or swift in your case. It's surprising that the parents/guardians weren't dealt with too.
