I'd endorse everything `Nelsonretreat' has to say with the one rider that, whilst it's true that the West Coast can be very wet, particularly in winter, it also provides great opportunities for wonderful images. And, in good weather, it can be very, very good indeed. I'd also concur with the comments about motorhomes, particularly if you aim to go to some of the more remote parts (which, in my view, are the best). Depending on the size of your party a decent 4WD SUV is well worth considering as it will allow you to venture further and see more. The down side is that you'll then need to find accommodation but, at the time of year you are planning for that should be no problem, unless you pitch up at a ski resort. Cost wise, the difference is probably not as great as you might think.
