We are going to Wanaka late August for 6 days. Usually we take a shuttle van and lump our stuff in the trailer and off we go. However this year we'll have our 9-month-old and my sister coming along so looking at renting a car. So what could you recommend if we want the following: ski rack childseat enough space for 3 adults + 1 baby and their luggage snowchain I wonder if we need an AWD car to navigate up to the mountains? We'll be skiing at Snow Farm. The cheapest deal that has all of these features is around NZD500. Does that sound ok? Thanks!
