We will be on our honeymoon staying for 5 nights. We are in our 50's. We like to relax in sun by pool and beach, shop, dine and wineries. love to walk around and explore on our own. We will have a car not sure if we should use or just park it and walk and use bus and boat to islands nearby. We are going in mid Sept. We are not big on tours or museums but don't mind short tours or cooking class for example.
Absolute must is to check Positano. Easy to get by a boat. If you are not short on finance, I would recommend to move by boat along the Amalfi coast since it's faster and more fun. Though a bus ride at least once along the cliffs of the coast is a must too. We stayed in all towns along the Amalfi coast during the stay last September, so Positano and Amalfi are the best, but give a short walk to get to Atrani (just some hundred meters, really) the smallest village on that coast. Love the small beach there. When in Positano, take a water ride to a hidden restaurant Da Adalfo. Love it. For a more relaxed evening, try one right on the beach. An old restaurant with great sea food and long history. In Amalfi Coast visit the central church to see where the St. Andrew is buried, one of great places for Christians. The roads are really windy there and despite low season traffic is pretty heavy so you must be really careful on the winding turns of the mountain road. So think twice. In any case it's amazing place, so you will be happy anyway :)
