Life has a funny way of re-arranging your priorities. So keep that in mind.
After my sister got her degree in journalism, she took a year out, and got in touch with a charity called Restless Development, and the long and short of it is that she went to South Africa for three months teaching English to students over there. (And I think it came to about £850 all in, which considering everything really isn't that bad in terms of price) So something along those sorts of lines may be of interest to you, rather than doing the travelling for the sake of it. And a perfect opportunity to learn about other cultures, languages and societies. My sister considers the experience as one she won't forget.
