Great trip! As you can expect, if you want to discover the island you have to sign up for a tour in a minibus, where they take you to different places, let you out to look around, then get back in the car. The first stop is the caves, pretty awesome. Our guide knew a whole lot about the island, he told us anecdotes, fun facts as well. He took the smaller roads, some not even on the map, so we had a better view than if we were on the highway. We almost went a whole round around the island. We had a lunch included during the day, we went to a nice little restaurant. You could order something à la carte, or they had an offer for soup+main course (4 or 5 options)+ dessert + drink +coffee for 14€. At the end you get pretty tired, eventhough basically all you did was sitting in the car. The weather is very changeable, you can never know what you'll see when you get out of a tunnel. I advise you to prepare more clothes, you can leave them in the car when you don't need them.
