At our wedding venue, guests have to get there by car. The vast majority of guests either live within 20 minutes of the venue or will be in a large airbnb at a place a few miles down the road.
Recently, my parents strongly encouraged my fiancé and I to consider switching from open bar to cash bar/no bar approx. 60 minutes before the end of the reception. I.e., open bar would be available for guests to enjoy from cocktail hour all the way through some dancing (roughly four hours). I think their hope is to curb drinking before folks have to drive home/to the after party. I'm unsure, as I want to look out for my guests' well being, but I also believe they're capable of making a responsible decision when it comes to drinking. Fiancé and I are paying for everything in the wedding, but I'm an open book when it comes to my parents' advice.
Has anyone hosted a wedding or been to a wedding that used this system? Thoughts on how you as a guest would feel, or would you care at all?
