Also heading off early 2014 hopefully but in the opposite way as I'm from the UK! Asia I thin is a must and has so much going for it at very good value it seems.
Would you want to work abroad to extend the stay and earn whilst you go? That's the route I'll be taking.
Good luck planning, it's truly exciting and although it seems ages away, it really isn't!! I joined here in June after my trip around Europe and already it's almost November!
