We have postponed our trip to MP from May to Sept because of train situation. We are planning to use Perutourism for our trip to Cusco, Sacred Valley & Machu Picchu. Has any had experience with this company. We do not want to take this trip if the Vista Dome train is not fully operational by then. We are senior citizens and are not interested in a lengthy bus ride to the train. We will definitely got to Peru in Sept but perhaps will head north if things are still shaky in MP. Do not need additional risks. Please advise.
