I know this is a long way off but I am contemplating going to New Zealand over Christmas 2010 and doing the Scenic Southern.Is It A Tour worth doing and what are people really like on a Contiki Tour Considering I have not been on one in over a Decade And Vietnam Highlights This Year will be my first one since 1999.Any help or advice would be most welcome and by the way I am also a non smoker and non drinker.
