Shetland

<p>My husband and I spent a day in Shetland while on a cruise to Norway and beyond. I had a kind of mystical response to the landscape, unusual for me!, and want to spend more time there. Does anyone have ideas about the best way to spend a week, or thereabouts? Hotel, B&amp;B, self-catering? We don't want to rent a car, and may even be too old for that, 70+; is the public transportation sufficient to get a look at the islands? </p>
