We are having a wedding, 150 guests, how much beer, wine and liquor do we need..full bar...stations dining

Your guests will drink approx. 1 drink per peron per hour, 40% will have wine, 40% will have mixed drinks and the other 20% will be drinking beer. Estimating that our event is 5 hours, we would suggest getting 60-65 bottles of wine, 3-4 60oz bottles of vodka, rye, and rum and 2-3 60oz bottles of gin and 6-8 cases (24 packs) of beer. Remember that you can always take back any unopened bottles of liquor to the LCBO.
