We are having a formal wedding at my parent's country club. Looking at the current budget we are planning on having an open bar all night, but with beer & wine & champagne only (red and white wine). It is a cost saving measure. To have a full open bar with liquor would increase the bill by $4,000. We are paying by the head, not based on consumption and we cannot bring in our own alcohol.
FI's family are huge drinkers and I know they will frown on this (they are not helping pay for the wedding at all). They also have a bad tendency to get wasted at family events. We we recently at a wedding and I heard his uncle say "Is this event beer & wine only or can I get a REAL drink at this wedding?" and it wasn't an innocent question, ya know? He didn't mean it in a nice way.
I'm worried my "cost saving idea" is rude or tacky and that I'm going to upset my guests and that they will think we're being cheap or something. Am I just being paranoid or is this actually a big deal and I should take another look at how to stretch the budget?
