The Alcohol Debate

The debate is not whether or not to serve or whether or not it is an open bar. Rather, we were deciding between buying our own alcohol or having the vendor provide it. While we selected a caterer that didn't even allow us to buy our own, we had decided against it before the tasting. We thought that even though the monetary savings are considerable, the logistics of everything was too much for us (mainly me, even though it would probably fall under B's list of responsibilities).

We would have had to:
a) figure out how much of every kind of alcohol to purchase - though I did find this drink calculator from evite. Although when I put the information, the quantities seemed low but I don't know if that is a flaw in the calculator or in our guests.
b) coordinate delivery no more than two hours before the start of the ceremony
c) have all left over/unused alcohol removed that night

In the end, we figure it is best to leave it to the caterer as they will know how much to bring and will need to figure something out on the off chance we run out. I have seen a wedding run out of beer before so don't tell me it can't happen.
