My sister and her husband from UK will be in Queenstown for a conference for a week in February. They then have just over a week to visit friends and explore the South Island. They are thinking of then going back to Queenstown to fly on to Sidney. I would have thought that once out of Queenstown it would be better to fly out from somewhere else - Christchurch? What do you think? Would you go back to Queenstown to fly out?
