We visited Positano recently on a one day excursion out of Naples. I fell in love with it. So we would like to come back on a longer trip. In your opinion, what is the best time to visit Positano/Amalfi coast for a group of adult friends (we are all in our 50's & 60's)? We want to use it as a base for day trips along the coast. If you have a suggestion of an even better city as a base, please suggest that as well. Thanks in advance for your help.
