I really want to host an open bar event, which would be coming out of my pockets because thats one aspect my parents won't pay for, and I'm okay with that. My dilemma is whether to do it. We should have roughly 145-150 people, wedding party included. The venue doesn't have a set amount to charge for people. The way they do it is to tally up the total amount spent on all alcoholic beverages (soft drinks are already included in our catering bill). Does this seem like a better or worse option? Should I just avoid it all together and use the money for something else? Especially since we aren't sure how much money it would cost?
