Award seats for this many travellers when you don’t have status is always problematic ? It isn’t clear just how young the children are though, as I feel this will impact heavily on how you transit around from hotel to embarkation point and vice versa. Especially as you say you’re carrying a number of larger bags.
New Zealand is a country (IMHO) which improves in the experience with the ability to have some independence when travelling about. However if you’re not a confident driver, and you have been reading about the foreign (mainly Asian tourists) drivers and their lack of skill in negotiating NZ roads, it may be just as well that you don’t drive yourself. That said, if you grew up driving in Oz, then hiring a car in the South Island, taking it out on your own for an hour or so to get back in the groove shouldn’t be too much of a problem. The South Island is worth the effort to see by car vs coach. The ability to stop somewhere for a family Kodak moment , or spontaneous meal stop with a view to die for, is worth the effort. Even when I travel in nz I hire a larger SUV if there are more than two of us. On our last trip we hired a RAV ( just the two of us) suv. Lovely car, great safety features and very comfortable with loads of luggage space. Car hire in NZ can be quite dear depending on when you visit.
IF you’re not driving in ZQN (and a car is really important if you want to see things away from the city) then make sure you’re staying in a hotel as close as possible to the centre of town. The Crowne Plaza is my number one pick for this. (Many places are a very steep long walk from everything) Walk out the front door, across the road and you’re in the thick of it. The Hilton is out of town, but does have shuttles and a boat into town. If staying in queenstown I would suggest a visit to Arrowtown, with a stop off at Amisfield winery and restaurant if possible, and if the weather turns sour Dorothy Browns Cinema is a good place to escape to. Plenty of places to eat and the tourist shops offer a good range of souvenirs and other local goods. A day trip on the Earnslaw is well worth the effort and there are plenty of walking trails by the lake. If going up in the gondola in ZQN, there is a buffet restaurant at the top. Buy your tickets for the buffet when you buy your gondola ride tickets. There was a discount on the price of the lunch. While I’m not normally a fan of buffet lunches, they are great for kids as they can eat what they want. And the buffet offering was surprisingly good value and good quantity in my opinion. Add to that the amazing view from the restaurant it’s a good day out.
Speaking of restaurants there are plenty of options in ZQN. From Fergburger to Botswana Butchery.
If you’re into your wines, there is a great place to buy and taste wines nearby.
Mrs GPH likes the coughtail bars which abound as well.
We liked to eat away from the Hotel, there are great cafe places which do great breakfasts.
If you break up your (road) trip to CHC there are thermal pools in Tekapo. (I only just found this out myself recently). There isn’t a great deal more to do there other than enjoy the view and visit the church of the good shepherd.
CHC is a prett town, and while there is still lots of reminders of the earthquake, there are still things to do. The Antarctic centre near the airport is a favourite of Mrs GPH,
It doesn’t look like you’re in AKL for long, and if it’s literally a matter of hours, there is an airhotel on the doorstep. Getting to and from AKL airport can be a real pain in the rear.
I’m with BAM on the train Vs Coach option. Frankly it might be worth the experience for your children (and you) to be without WiFi access for a few hours,the lost art of conversation may help as will the novel idea of a book. Or just soak up the view between chats.
That’s my two cents worth, but given we are probably a bit different in age, some of my ideas may not suit.
Hope you all have a lovely trip and it is everything you plan for.
