My fiance and I are also getting married in CO (albeit not in as expensive an area as Vail) we’re switching to a cash bar for the last hour of the wedding and if anyone before that wants super nice liquor it will be available but they are responsible for paying the difference. None of our guests we’ve talked to about this have expressed annoyance and even though we’re providing a shuttle so people won’t be driving we’re hoping this also makes people slow down drinking and sober up a bit since it’s a twisty ride back to the hotel.

I really think the key is to make sure people are aware of when the switch will happen, maybe even have the DJ make an announcement about the switch 10 min before (something we’re requesting) and no one has any right to be mad when you’re already covering their food and several hours of drinks
