Yeah, I'd at least double the beer.
Remember, most liquor stores allow you to return booze as long as it isn't opened, so I'd say if cost isn't really an issue, buy more of evertying and return what you don't use.

It's already been said, but you shouldn't be too worried about running out of booze, but running out of one or two kinds of booze.

Of course if people are going to complain about not getting the exact free drink they want, you should kick their ass out of your wedding.
