Things to Bring When You Travel. On a more practical note, here's my list of things to always take along when traveling.
Note that I'm talking about longer-term travel on a strict budget; if you're only going for a few days, or you've got money to spare (or a corporate sponsor), you may well want to take along less and, if necessary, buy things wherever you're going. Thank you to everyone who's made suggestions - if you think of anything else, please e-mail me! There are several sections here: Everywhere Needs, Hostel Specifics, Practical Things (weather-based), and Optional (things which aren't necessary especially if you're a light packer, but which I personally would bring along).
And also, I assume you don't need my help to remember your toiletries, underwear, and other such obvious things... BUG - the Backpackers' Ultimate Guide with hostel reviews and budget travel destination guides. Travel Guides - World Travel Guide. Art of Travel.
