So I'm having a little bit of a delimma. We are hosting an open bar for our reception. Cocktail hour is in another part of the building and then the ceremony space will be flipped for the reception. Since the bar will need to be moved from cocktail hour to reception space, my coordinator and the venue coordinator suggested that I only serve beer and wine for cocktail hour. Their reasoning is that the bar used for the reception can be set up with garnishes, liquor and mixers prior to guest arriving so that only the beer and wine will need to be moved from the cocjtail space and it would make a smoother transition.
My problem is how do I reiterate this to guests? Invitations have already been sent so I can't add it to the detail card. I could just have the bar tender inform them or put a notice on our website they can view when they rsvp, maybe a sign for the bar stating more options will be available for the reception? Do I need to tell them anything at all?
