Karen, have no idea what Sheep World is like, but you can't go to NZ without visiting a sheep farm! Only place most people will probably go to see one! It was one of the highlights of my trip on a leg of the WC in '05. Wineries are everywhere, and I'm tired of them after France, Chile, New Zealand,and Africa, but those other places don't have sheep farms! The one we went to (through Regent) was a private farm, and it amazed me how the owner could send whistle signals to his dogs waaaay up in the hills. Certain whistle sounds made the dog turn left, right, go up, go down. And watching those dear dogs work so hard and furious getting the sheep herded and back down to the pen was fascinating to me! I hope this is not a "petting zoo" type place where you just get to see them shear a sheep, but more a working farm, as that is what I am talking about. Don't mean to horn in on your own plans, as I'm not even on this cruise. Just passing along my personal experience on my visit to NZ.
