We are planning on having beer and wine at our reception but we aren't having an open bar all night long, at some point it will turn over to a cash bar but would like to serve some on our tab. Right now I have 2 kegs of beer reserved and about 30 bottles of wine for 200 people and that is obviously not enough. The last thing we want is to offer some free alcohol and then run out right away. But we also don't want to pay for everyone to get snookered on our tab. If we could stretch the alcohol for 2 hours, that would be perfect. And then go to cash bar. What did you guys do and how much did you go thru? Is there any certain rule of thumb out there to help us decide how much more we need? We will have a fair amount of young folks at our wedding who will drink but then we also have quite a few old folks too who won't drink or not much.
