I've been struggling w/ being OK w/ this idea. Due to several issues, but mostly budget constraints, my FH & I had decided to not add on the open-bar option for the whole night. Instead, we are offering 1 hour of open cocktail bar, 1 glass of wine served w/ dinner, a glass of champagne passed for toasting, & cash bar for the rest.
We wanted to forego the full open bar to use the money towards upgrading our venue package to filet mignon entrees instead of just chicken, photo booth rental & other stuff to make our day special.
My FH is totally fine with not covering the alcohol for the whole night, as a majority of his family is Muslim & does not drink. At first I was OK with the idea as I don't care to see anyone get wasted on my dime on our special day & act a mess, but now I'm overthinking.
EDIT: Called the venue and she listed a lot of options from consumption to putting a set $$ amount down toward drinks. Also got an agreement for flank steak instead, saving $480.
