Thanks for your suggestions/advice.
I checkup Queenstown from internet and found that it is about 7 hours drive and looks far.
1) How do I get fr Christchurch to Queenstown if I don't drive?
2) I believe there are bus/coaches which I can book but I can't seems to find their website after trying for quite awhile, Please help.
3) I need to find out does the bus/coaches has destinated stops along the way for rests and pictures?
Queenstown is more southwards, what would the weather and temperature be between 7 Jun to 13 Jun.
