Those that know me personally or through my blog will know that i'm uber organised. I compiled this checklist a few months ago and thought I'd share it. Please note that it is female-skewed but feel free to cross out the items which aren't applicable to you. For short trips, you'll probably only need a third of the list.
Hope this helps :)
