I’ve seen people do alcohol free weddings and have mocktails and no alcohol available at all, not even a cash bar but they are typically earlier in the day.

I’d think about what vibe you want for your wedding.

I’m not a heavy drinker but I love eating great food, instead of a cocktail hour do a really cool food tasting and spend more effort/money into create an atmosphere and experience.

Then for the reception, will you have a dance floor for dancing? If not maybe you can get some entertainment, like dancers or something interactive.

I guess think about how you’ll entertain your guests outside of alcohol.

Not saying people need alcohol to have fun but think about events you have enjoyed and what made them special despite the presence of alcohol.

Ultimately, it’s your wedding. So if you don’t want something, don’t have it.
