The boat trip itself was very good, I would have rated it 4 stars but the process of getting to Sorrento (where the tour started) was not great. First it's a very long drive on curvy roads. The driver didn't give us any instructions and we had to make a bunch of random stops to pick up people that also seemed kind of confused. Then we got dropped off on the side of the road and had to walk to the lift and the port. We eventually got on the boat 2 hours after we left Amalfi. We didn't get to "discover" Sorrento. But Capri was nice. Once we were on the boat it was fine and the trip was good. So if you are coming from Amalfi, be aware that it is a long process to get started. You might be better off taking the ferry right to Capri or opting for a private excursion that leaves from Amalfi directly.

My quick advice is to book these types of trips locally, when you can communicate directly with the service provider. Don't panic, there will be availability. A vendor with whom you book more directly will feel empowered and willing to give you the best experience you can possibly have. By booking through viator, I feel the vendor did not feel empowered to advise us of poor marine conditions on this route. Essentially, we paid over 600 US for a direct trip to Capri no sightseeing at all that should have cost us no more than 200 via express ferry, the most expensive option. In addition for paying WAY TOO MUCH, we enjoyed watching more than half the small group of nice people accompanying us puking off the sides and inside the cabin of the boat. They were suffering mightily. When I contacted viator, all they did was forward my message to the vendor. We did not take the return trip back to the Amalfi Coast Why would we want to get on that boat again? We paid 100 additional to take the ferry back. Yes, the vendor used our decision to stay and enjoy the island as evidence that they delivered the promised service. Read the description. All they provided was portage. They cannot take credit for our enjoyment of the time on land. Taking the ferry would have given us that same experience -- much more cheaply. Viator does not provide any guarantees on its service. They are just taking the commission and creating a buffer between you and the service provider. When the cost is this high, don't risk it!
