We in fact made a liquor-less chassunah just a few weeks ago. Our michutanim did not want to pay the outrageous fees and we were completely fine with that. There was wine served by the hotel wait staff at the meal as the only alcoholic beverage and it was only served in moderation to those who appeared to them as 18 and over.
I received a total of 4 comments, 2 were made as simply as an “aside”, one made a prolonged comment and one was persistent until he got some alcohol (the next day). Out of 450 guests I would state that it was NOT a major issue in any way. Perhaps if everyone stopped serving hard liquor, the families would save a great deal of money, the behavior exhibited by the males present would be a greater Kiddush Hashem, and people would stop feeling a sense of entitlement, that a simcha owes them the booze.
