This tour was advertised as half-day but it didn't start until 2 and finish at 7 pm. The description of the tour didn't specify that the trip would be outside of Cusco city. The guide for the tour was very informative, but unfortunately I had to leave half-way through because my flight was at 8 pm. You also have to pay for your own tickets which are not included in the price. Once again Viator sub-contracted out another company who then sub-sub contracted out another. You can probably organize this tour on your own when you are in Cusco. There are plenty of local tour operators with probably a better price. The tour includes a visit to the main cathedral, the dominican church which was the main Inca temple in Cusco, and a visit to an Inca site outside of the city.
