I am planning my sisters wedding and they have to bring in their own drinks.. Adult only reception.. RSVP's of 300 and they are having bud light (keg), wine (red & white) franzia boxes 5 liters, Sky vodka, captain, southern comfort, and mixers. Of the million drink calculator out there, none of them come out the same at all. Of course no bartenders or reception coordinators will help give me numbers because they want us to go through them.. How should I go about figuring this out? I would say 45% beer, 35% liquor, and 20% wine crowd.
