I am trying to decide whether to take a tour from Naples to Sorrento and the Amalfi coast on a Sunday. I don't like to do cruise ship excursions because I don't like the big tours. Any suggestions on a tour besides Viator. Is it feasible to go on a Sunday? We are in port from 7-6.
The obvious answer to avoiding big tours is to hire a private guide for your group.
Viator is not a tour guide company. It is a third party consolidator.
Try Mondo Guides, which has a relationship with Rick Steves and meets you at the cruise port:
