Not even close - and I am NB so no extra allowance. Currently travelling for 25 days in both hot and cold climates and luggage is around 14kg (+carry on) - and that's only because I have picked up some books along the way. Mr Romney is about the same, kids (teenage girls) around 12kg. We do a lot of public transport wherever we are, so the rule is if you take it, you have to be prepared to carry it. It's brilliant at stopping the kids wanting to buy things the whole time - but I normally do plan some shopping time towards the end of the trip for them to look forward to, and we have a few kilos extra between us on the way home.
