So my Fi and I want to host the bar for our guests and are struggling over whether to do open bar per person option or whether we should just pay on consumption. We will likely have approx. 90 people - about 7-10 of that group will be under 21.
I think our group will definitely take advantage of the open bar but most will not drink to excess. Some of our group - while over 21 - don't drink at all. If we pay per person it's $30 per person for the whole night for alcohol and soda, etc. for anyone over 21 and $12 per person for non-alcoholic (minors). Drinks run about $4 or $5 for beer, $6-$12.95 for wine and $7-8 for cocktails and martinis.
What are your thoughts? What is the better deal? Including taxes and fees we're looking at $3100 for open bar per person. What do you think we should estimate if we pay on consumption? Thank you all in advance!
