My fiance and I are hosting a DIY drink station at our wedding as we're catering ourselves. We will buy a bunch of sodas, liquor, and a couple kegs of beer, along with champagne for the toasts. We will have cups to mix drinks, garnishes like cherries, some grenadine and other mixers, etc so people can make their own mixed drinks. We have a guest list of 160, 20 are kids.
I found an alcoholic drink calculator online for beer and liquor, but what about sodas? We're planning on keeping it fairly simple... coke, diet coke, sprite, ginger ale, orange soda, plus we'll have drink dispensers of lemonade and iced tea. How many of each soda should we purchase?
