Queestown is our top destination in New Zealand. Better to secure 2-3 days in here. Road to Te Anau is amazing. For the photographers, spare a full day for this road. Milford Sound is also nice. You may have boat trip in here.
You may not be able find staff in some hotels or hostels after 5-6pm. Even you may have booked or paid. Doesn’t matter ! Tell them that you are going to arrive to the hostel late. No need a surprise like the one we had.
Always keep your tank full in New Zealand. In some regions, we could not find open petrol station maybe for hundred kilometers.
