We're confused about Kangaroo Island, and thinking about skipping it because we don't know how to do it. But I really want to go there! First question: what's the best way to get there? We'll have a rental car from Sydney but it seems that any rental car from Sydney is not insured on KA. And if we pick up a new rental in Adelaide, it won't be insured on the ferry trip. Is this something to be concerned about? If we fly to KA, there are luggage restrictions and we'll likely have too much weight because we're spending a month in Australia. If we go across as ferry passengers, can we pick up a rental car at the ferry on KA? Second question: Is Kangaroo Island worth doing on your own? Is it possible to see lots of cool stuff without being part of a tour group?
