We had this problem a few years back. I fixed it this way; A party is a good opportunity (sp?) to try something new. We bought a bunch of different beers that are made locally and incorporated them to the party theme. Some people even brought their own kind of alcohol to try. Result was that the drinks were smaller and more diverse. By the time you found something you really did enjoy, chances were that there wasn't much left to overindulge. Now we also do it with the food. Some mixes are bizarre and others pretty good. Hope this helps.
