Hi Clonback.
My wife and I stayed in Sorrento in a really nice hotel and did a day trip to Amalfi coast on the local bus , which we were able to get off in any of the towns along the way , and then back to Sorrento. We found this a lovely way to see the lovely towns and as many as we wanted to see. . You could do more than one trip to see as many towns as you wanted and for a good price . I hope you enjoy the trip, we did, Sorrento and the Amalfi coast are beautiful.
