This is a page that will (hopefully) grow a lot soon. I am a bad planner, and usually leave it right until the last-minute or tag along with super organised friends. But I do figure out a few things along the way. These are some websites that I have found useful.
Reviews and quotes for travel insurance.
A starting point to find out visa requirements.
To find out the latest exchange rates.
For cheap flights around Asia.
And a huge collection resources can be found on the Matador Travel Forums.
