hi, sorry to ask the same old question but here goes. We are 2 adults and want to spend approx 2 to 2 an a half weeks, over the sept/oct school hols (mid sept to early oct) around our most favourite part of the south island, queenstown. However this time we want to definitely do the glaciers(heli hike if budget permits) and like the 3 day itinerary from real journeys from te anau, being milford sound scenic day cruise, doubtful sound overnight cruise and the te anau glow worm caves. We're not sure if we should fly in via Queenstown and out of Christchurch or Fly into Dunedin and fly out of Christchurch or just simply fly in and out of Queenstown. Any advice would be greatly appreciated.
