I went to Sydney, and Queenstown New Zealand a few months ago.
Queenstown NZ is for sure my favorite place I’ve found on earth so far.
– stay at the Novotel if you can. It’s right on the beach, and amazing. Also all of the hostels are also fantastic if you’re that type of traveler.
– if your phone is unlocked, hop into Vodaphone and grab a $30 prepaid SIM (incl data and talk/unlimited texts) hotel internet is expensive.
– thing to do: Fergburger. Go up the gondola in the city. Take one of the boat rides. Do a Lord of the Rings tour even if you don’t like the movies.
