I personally think people need to get over their expectations of unlimited alcohol at a wedding, I don't understand the attitude. I attend a wedding because I want to share in the joy, I bring a gift because its the thing to do. I don't do either of those things because I expect something in return such as meal or unlimited alcohol. I realize my attitude is not shared by all
My cousin had a hosted bar for 1 hour for 100 people, that one hour was close to $2K after that it became a cash bar, I had no issue with it.
I've been to all types, no booze, mixed drinks, beer & wine, hosted bar, no host bar and a mix of both. The only thing I like to see is that as a guest I know ahead of time if I need to be bringing drinking money with me or not.
I think in this day and age the couple should do what they want to do that they are comfortable with and can afford.
