In a week you can have a quick look at everything to get a taste, but as others will say (like pearcy and gu camper) you can spend months and still have more to see. Usually you'd think a circuit is the most logical way to go but as nothing is too far from anything I'd suggest just getting lost and going wherever you feel like on a whim.
What type of activities are you guys into? Short walks to lookouts, fine dining, history....?
