We booked our guest for an 8 days tour. for the first 5 days, everything was good but in the 6th day, the schedule was to go to Grand Canyon and Hoover Dam, when they tried to board the tour bus, the tour guide by the name of Roy told them that they don't have room in the bus, so they were left behind in Las Vegas the whole day.I think that was wrong and they can't just simply leave people in the middle of no where.I filled a complain a week ago and it seems to me that no investigation was ever done. l deserved answer.
