My husband and I were traveling in Cornwall, England with two friends and being from the US, we were uncomfortable driving on the left side of the road so we decided we needed a car and driver. Another friend had highly recommended Viator tours to us so we found two, one-day Viator Cornwall tours providing a skilled guide/driver. The two tours were in the two areas we wanted to visit but did not necessarily include some things we wanted to do and see. The Viator website indicated that the tour could be customized so we asked to speak to the guide ahead of time in order to plan the customization. A couple of weeks ahead of time, James (our guide/driver) for the two tours, contacted me by email and we worked out a plan for both days that met the needs of all four of us. We were very pleased with Viator, their website, their basic tour design, the way the payments were handled and the ease of booking. We also cannot speak highly enough of James, our guide. He picked us up right on time, was extremely accommodating, had a very nice, clean vehicle and even provided water as well as rain jackets and umbrellas when we encountered bad weather. His choice of places to have lunch were excellent. Not only did his suggestions give us a sense of the local cuisine but outstanding examples of it. We would give James and Viator the highest rating possible.
