W&B may well be ok outbound, but return will be difficult - the temptation to overstock on heavy beverages is too great.
Personal experience of this - I went with two work colleagues. We stocked up, my having given an allocation for weight and positioning. The inevitable happened; too much booze. Their solution? Drink the excess... Seemed great until I pointed out they were merely redistributing the excess weight - even after ditching aluminium packaging. It took ten minutes of argument to prove my case to them. Both exceptional computer scientists.
