I think that depends on context a lot. If you've got room to roam a group of drunk people that keeps to itself is rarely a problem. I've been to conferences where the party was in a small, crowded and loud area and I just didn't feel good because I couldn't move away (although I do drink). On my own conference, we take great care that beer is served in open areas and that everyone can choose where he sits around. That works very well. It is an issue, it is one that can very easily be solved with a bit of open-mindedness a bit of care.
