What about some wine? I don't drink liquor and am not a huge beer fan, but I do enjoy a nice glass of wine. I'd do a bottle or two of red and white (although you know your crowd, my friends are much more of a red wine crowd).
I agree with LSU, wine is always good to have around. I am a big red wine drinker, not a big fan of white, but want people to have a variety. We had Christmas Eve last night, since DH and I are in law enforcement and I have to work. We had two adult tables and each table had a bottle of red wine and white wine. Then for the kids, I made Crock Pot Hot Chocolate and a non-alcoholic punch and soda.
