How much alcohol should I get for the weekend?

My friends and I are trying to see how much alcohol we need for a 3 day 3 night trip. We are 4 of us , one of us doesn’t drink that much (2-3 shots), 2 of us are heavier drinkers (7-10 shots) on of us drinks normally? (3-6 shots) we were thinking we would get a 12 pack of twisted teas, a 750 bottle of vodka and Bacardi, and a mickey of tequila. Y’all think that’s enough or too little. We are also planning on smoking and being drunk the whole time. Thoughts?
