I had relatives with that mentality, which is the excuse we used for not having an open bar at our wedding. (After pressure from one side of the family to have one)
We’ve been on exactly ONE cruise (to Alaska from Seattle). My wife initially bought each of us a drink package for something like $250 each (maybe a lot more). I asked her “Why would we do that? We hardly ever drink!). She cancelled those add-ons. I think we each had a couple of beers and wines.
