We had about 2 liters per person and the nice lady at Sand Point just kind of laughed and said no worries.  I think she was surprised that we told her we were over.  Of course we thought legal was 1.75l, when in fact it is less, per the post above.

As for this year, we are going to try and pare that down a bit, the stuff weights a ton.  I might try some bacardi 151 vs the good captain.  Our trip bartender goes a little nuts and tends to burn the drinks, we'll have to keep an eye on him if we start using the really hard stuff.
