We booked our tour directly through E-Ko tours rather than through our cruise ship. it was a lot cheaper this way. however due to a large storm the ship wasn't able to dock at Picton. we were only given 24 hours notice of this and immediately contacted E-Ko tours. They kindly advised us there was no refund available as 48 hours notice wasn't given. However those booking through the cruise liner got a full refund. Very poor service considering it was beyond our control.
