Thanks for your replies. We are renting a car and our schedule is;

Te Anau - 3 nights
Wanaka - 2 nights
Fox Glacier - 3 nights
Arthur's Pass - 2 nights

Any further suggestions welcome. We are thinking of booking a helicopter flight over the Fox Glacier and Mount Cook area - is this worth it? We have had to cut out Kaikoura, as getting the flights organised was tricky. It would be great to touch base with fellow LF'ers!

Cheers, David
