My fiance are in a rut with what to do about alcohol at the wedding. We are looking at around 130 guests and most of the people on my fiance's side of the family do not drink for religious purposes (we counted about 40). No one on my side of the family are heavy drinkers, but they will have a drink or 2 if it s there. I cannot justify having an open bar and throwing away that much money on 40 people who will not even touch the alcohol. My family thinks that cash bars art tacky and not proper etiquette. We were looking at running a tab and setting a tab to a certain amount of money, but have no idea how soon we would reach the tab. Any suggestions on what to do here? Thanks!!!
