If you care enough to invite people to your event, you should care enough to make sure they get home safely. Provide transportation for those who need it. If that isn't practical, offer a place for guests to spend the night even if it means your couch or your floor. To assist with student organizing, here are a few guidelines. Students should enjoy themselves, but as responsible organizers everyone should be concerned about the responsible use of alcohol.
Alcohol abuse has a devastating effect on people and all aspects of their lives.
This only encourages irresponsible drinking. Soft drinks should be predominantly displayed and made available free of charge. Students who have had too much to drink should be denied the purchase of alcoholic beverages. To supplement paid security details a few students must be designated to act as counselors to students who have had too much to drink or seem to be getting out of hand. These students are not 'bouncers' or 'security' but are there to help their peers.
