I know a stack of people who have been travelling, My missus is currently in South America. There are plenty of good websites etc to find out where and what you want to do, when my sister wakes up i'll find out some for you.
I've had lots of friends that have started travelling and never come back, these places are so beautiful and refreshing from the UK people just want to stay and many of my friends have, one of my mates who did motorsport filming over here went travelling and now is in his second year over in I believe now Japan (he moves around lots, he started in Malaysia) doing motorsport and advert filming/editing, got another couple of buddies in Australia 1 now married, its blooming crazy. Its one of those things that I think if I went away I wouldnt come back, as we all know the UK is a pretty dire place to live right now.
I think what im trying to say is, be careful what your going away to do just travel or maybe in the back of your head looking for a future else where.
