On the back of the other thread, which is really interesting, about places you wouldn't want to go back to, either because it was unpleasant or because you saw it all while there, I thought it would be interesting to know where people WOULD go back to.
I'll start:
New Zealand - beautiful, varied scenery around every corner. We only did parts of the South Island and I'd love to see more. Three and a half weeks were not enough!
Edinburgh - we do go back there regularly, it is a beautiful city with an amazing vibe.
Berlin - I loved it and wouldn't mind revisiting one day.
