That was my favorite part of our trip two years ago.
We went to Florence, Sorrento and Rome.
Stayed in Sorrento for 3 nights. took a car tour of the Amalfi coast one day. Walked down to the water for the “famous” sunset photos. Had a boat tour to Capri cancelled du to rain and rough seas unfortunately but it gave us more time to explore Sorrento. Went from Rome to Venice to Firenze to Sorrento. Got to see Tuscany, Siena, Pompeii as well, total whirlwind.
