We used Viator for three different port tours. Did NOT want to go into Naples as we don't like the big city, crowded feel. We hired an single vehicle with private driver who took us down the Amalfi coast, stopped for lunch where he recommended, made several other photo-op stops and did a little shopping. He was SO nice and spoke good English and gave us lots of information. Very professional, clean, and neat. Vehicle was very clean and nice, too.
