When I look back at this trip I have mostly positive thoughts, although there are also some negatives. I'm going to be completely honest here because I believe that potential trip-goers need to have a realistic perspective and honest opinion.
Queenstown: This place is literally the best spot for young travellers. Its aesthetically pleasing, full of adventure activities and sights too see for people who like a slow pace and has plenty of hype for people who love their nights out! We were there for 4 days and it feels like home by the end of these days. The included activities included the Shotover Jet (the most amazing experience! So much adrenaline and something that I will remember forever) and dinner at Winnies Pizza (this pizza is heaven!). Metime activities are expensive but some are worth it. For people that are starting their Contiki in Queenstown beware; most people on my tour started in Christchurch so they had spent 3 days together and had already booked their metime activities hence there was a bunch of activities that I wanted to do like the Canyon Swing and Ziptrek that I was not able to get into because it was all booked out. I did Minus 5 Ice Bar (recommended), Milford Sound (recommended; the drive was more amazing than Milford Sound itself), Shotover Rafting (I don't recommend, the rafting I did in the Tully river was better than this and definitely not worth $200+) and Skyline Dinner (something like a 18-course buffet- amazing!- and great value for money). Hidden costs in Queenstown annoyed me like transport (taxis, buses) and beware those of you that are not about the nightlife, there is nightlife happening every night and most of the time you feel pressured to join.
Franz Josef: We were going to do the Ice Explorer but it was cancelled due to a bad crash and weather. The Kiwi enclosure is not worth the $30 to get in there but the Hot Springs are definitely recommended! (so niceeee and a perfect way to warm up) Also, there is a themed party so make sure you shop in Queenstown and the theme changes every trip.
Christchurch: Did not get enough time here. We had around 15 hours here. Although we did go to Lonestar for dinner and it was expensive but the food was amazing. The ferry ride from the South to North Island was boring- have entertainment!
Wellington: Maybe my favourite stop. DO THE $25 DINNER/BAR! We went to Blend bar and got 2 drinks, a meal and dessert for $25. Drinks were $5 only and this bar had classics to dance to such as YMCA, the macarena and more and the bartenders conducted drinking games. This was the only night I got really drunk but had an amazing time! The next day do stuff thats free. Wellington has plenty! We did the museum and it was amazing and took up a good amount of the day.
Taupo: Taupo itself is lovely! Nice and hot compared to the South! We should have gotten another day here as it looked like there was plenty to do. The boat party was legendary. It was also a graffiti party so we all had to wear white shirts and buy markers and Sharpies.
Rotorua: I cant give an accurate description of Rotorua because I was sick and spent the day in bed. Although, Huka Falls was incredible. Do the OGO balls!!! And definitely do the gondola and luge rides! The Maori dinner was so interesting and insightful and included!
Waitomo: Awesome little small town. Most of us did the caves walk and its amazing. Others also did the Rafting and said it was a highlight of their trips.
Auckland: From what I saw by spending 5 hours there it was nice! Its got a great vibe and has lots happening. I did the Sky Tower Walk and I recommend this 100%, it's insane as well as the Sky Tower Jump!
Accommodation wise, here's the low-down:
Queenstown: Beautiful, 9/10
Franz: Average, not enough room for Quad Share, 6/10
Christchurch: Luxurious, 9/10
Wellington: Average, better than Franz, 8/10
Taupo: AMAZING, 9.5/10
Rotorua: Average, probably the worst, so hot! 5/10
Waitomo: Better than I expected, 7/10
Auckland: Didnt stay in accommodation, left this day :(
OVERALL, I DEFINITELY RECOMMEND THIS TRIP!
