Great idea! Anyone wishing to ship bottles home for any reason, pm me because I have lots of these wine shipping boxes in anything from twos to cases, they are here for the asking.
Also, transporting beer in baggage may be risky with the pressurized baggage compartments. Chilling the beer once you get to Can Jam will be a challenge as well. A bathtub full of ice and beer may have the Hilton folks trying to surcharge you. That was a nice and generous offer though but too risky for you me thinks.
