Queenstown land of the adventure pamphlets
Queenstown is awesome, the only tip I have is that we went on the K Jet boat over the Shotover Swing/company jet boat because it was an hour on the lake rather than a half hour. Also, there is a longer trip with a kayak tour attached to it thats like 4 hours that was the best value I think but I couldn't book it due to our itinerary/time constraints. The grocery store is very close to the center of town.
Insider Tip:Anything up on the mountain requires a gondola ride at ~$30, if you do the luge or zip lining try doing it in one day, and save yourself the extra trip up there. Also, if you are traveling north to christchurch, look into car relocations and apply while you're in queenstown. You can wind up driving a rental car back up to christchurch for $1/day and a free tank of gas. Learned about this after the fact and too late to take advantage of it.
