My wife and I spent a day with Carmelo touring the Amalfi coast and Paestum. He picked us at 8:00 and dropped us off at 6:00. The trip is expensive but enjoyable.
Carmelo gave us a brief tour of Sorrento and then took us to Positano where we toured on our own for 30 minutes or so. After that we stoped in Amalfi for 45 minutes. We had lunch in Paestum and had time to visit the museum and ruins. During the course of the trip we stopped at a lot of scenic overlooks for picture opportunities. The itinerary worked well for us in terms of how the time was allotted.
Monetti Taxi is a great option for seeing the Amalfi coast and Paestum on a day trip. The cost is high (400 Euros) but it’s reasonable in comparison to two separate trips or staying overnight in Paestum.
