That's true Beagle. Making the way down to the south island for a travel itself is a luxury trip already! But if you have already made the decision and planning for a unique experience, a campervan can give you one that is very differentiated from the normal motel/bnb stays unless you are looking at something super-luxury down there I have never been that luxury in my life so can't tell what that would be like. I agree with you, each to their own as I dream of going out for camping every weekend with my kid and sitting in a chair sipping my handmade espresso!
