that sounds like a great way to celebrate FWIW, it's exactly what i've done when having or going to ****tail parties in the past - we just specified what spirit people should bring so we had the right mix. one other friend who had a ****tail party asked us all to chuck in $10 but i kinda prefer the bring a bottle (even though it costs more - it could be a bottle per couple?)...the only thing would be if you had some non-drinkers
