Southern Italy itinerary critique and suggestions

My fiancé and I are planning a 16 day trip to Italy early July and have the following itinerary. Please critique and/or add any suggestions.

· Portofino 3 nights

· Positano 3 nights

· Capri 2 nights

· Cilento Coast 6 nights --> Is this too much?

· Rome 1 night (for flight the next day)

We are thinking 6 nights in Cilento might be too much and open to trimming that down to maybe 3? and possibly spending only 2 nights in Portofino as it might be too crowded. That would give us 3-4 extra nights that we are not sure where we should explore in southern Italy. Very open to suggestions.

Some background:

We are trying to keep a relaxed pace while exploring each area without feeling rushed

We will have a car so will be pretty mobile

We think Portofino and Positano/Capri will be crowded so looking for something more relaxed for the second half of the trip

We love the coast and exploring aithentic Italian villages
