FH and I would like to offer an open bar at our wedding serving beer, wine, and a signature drink or 2 but are worried that the cost can get out of control. We were going through how much it would cost if people had 1 drink per hour through out the reception and the cost gets expensive really quick. I'm sure not everyone will have 5 drinks but in theory they could have that many or more (we have a few heavy drinkers and a few who don't drink at all). But here is the question- would you be offended if the open bar was cut off at some point during the night? To help prevent all of our honeymoon food funds going into the bar what if we capped the bar at a certain dollar value and if guests wished to continue drinking it would be a cash bar?
ETA: I had called it an open bar but I guess technically it would be a limited tab bar offered with free non-alcoholic drinks all night. This would mean the bar gets capped at a certain dollar value unless approved by bride groom or designee.
