What sort of traveller are you? I find, as i have grown older that I tend to travel increasingly lighter. I used to carry everything but the kitchen sink when the DCs were young (before these appalling weight and size restrictions came in) and often found i came back with a really vast amount of stuff we had never used. I now find I am much more of the opinion that if i have forgotten something it will a) be easy to replace (speaking toothbrush or more socks) or b) can be done without.
I still spend far too much time on packing, ensuring i dont forget too many essentials, but end up with smaller and lighter cases (as long as my dear H does not get involved!)
