I am driving a rental car from Christchurch to the Hermitage Hotel at Mount Cook on Dec 27th. I am interested in finding out the best route to take and also what I should stop and see on the way. Is the 3-D Mount Cook film worthwhile? What about the Edmond Hilary documentary? How about the 'Church of the Shephard?' Also, I am continuing down to Queenstown a couple of days later. Any suggestions regarding route or activities on the way down? What is the best route from Queenstown to Christchurch? Thanks for your help!!!
