Looking at the pictures from the hosts of the evening that I'm going to, I guess that sounds pretty close to my evening/night as well (9 persons, 10 bottles of wine (5 white and 5 red), 2 bottles of gin, 2 of rhum and 2 of whiskey. Add to that a (secret) welcome drink, the bottle of gin that I'm bringing and at least one bottle of bubbles from each).
Good thing that New years day is spent in front of the TV (TdS, Garmish, New Years concert from Vienna and later the New years speech from the Prime minister)
