Bartenders - I’d love to hear your advice

Hello!!

My fiancé and I are getting married in 10 days, and we’re in the buying process for the alcohol. The wedding sub usually says 1-2 an hour but I figured I’d ask the experts who’ve seen it in real time. We’re doing a red, Cabernet, a white , Sauvignon blanc, whiskey on the rocks, lavender martini with Tito’s, blue moon and coronas, and coke and sprite as the other alternatives to mix with. The number of guests were at is 80 people. In your experience, how much have you seen people actually drink at a wedding? None of our guests are people we would assume would get slammed or go ham at the bar. I tried to do some probability testing with who would likely drink what, wine is probably the least chosen option, and liquor and beer being the most. I appreciate your responses!!
