I'd like to start by saying we are having an open bar for our cocktail hour and reception. We are also having a greeting station with apple cider donuts and champagne for guests before our ceremony.
Our venue asked if we would like to have the bar open as a cash bar before the ceremony (so for those early arrivers). I know that typically cash bars are no go (obviously), but what about in this instance? Essentially, they've said the bartenders would say something like "Currently we are a cash bar, but there will be an open bar beginning during the cocktail hour. You can also help yourself to donuts and champagne!" Is this in bad taste even if it's only pre-ceremony and there is an option for complimentary champagne??
