Thanks for the info. That's a relief. Given that we only have a few hours in Christchurch, car should be more efficient than bus unless parking is limited.
We are picking up a car on our arrive into Queenstown because our hotel is 10 KM from town. How is the traffic and parking situation in Queenstown? Should we wait to get a rental car and just rely on taxi (heard Uber is not yet in Queenstown) until we are ready to leave Queenstown?
In summary:
1. Stay on the left side.
2. Avoid driving at night through the mountainous area. Why drive at night at all when the views are so wonderful.
3. Watch for the drivers who did not get the message about the right turn law.
4. Watch for the speed limits. Pull over for the faster cars.
5. Pray to encounter the one way lane bridges to enhance my trip story. :-)
