I am on the same boat! We wanted to go with the international open bar for 15 per person for 5 hours and because we have 50 guests, that will cost us 3750 just for drinks alone! But just like you said, we have a lot of guests that don't drink, or that maybe will have 1 drink all night long, so we are seriously considering having an open tab throughout the night like some brides suggested. I just don't know if that is something that ends up costing more depending on how large your group is. If anybody knows how much the individual drinks go for and like Jenn asked, water, juice and soda? Thanks!
