How old is your daughter? I did Magic Bus is it kind of a cross between a tour and backpacker bus. My bus had people ranging from 18-50. The bus takes you from one town to the other stopping at activities along the way. It is sort of a pay as you go. You can spent as much time at each night stop as you like, you just have to make a reservation on the next bus. Or you can stay on the same bus you were on the whole way. Not fancy, stay in hostels, but think you can upgrade. Another similar company is Kiwi Experience. No frill, carry your own bag, sleep in hostels, but think you can get a private room. We loved it. Our bus even stopped in the middle of nowhere so the driver could watch the All Blacks play in a big rugby match. It was a blast to watch in a local pub.
