Dear clients, we are sorry that you were dissatisfied. You had a Mercedes Vito, a luxury van for 8 people, privately for 7 people, so that no one would infect you with Covid. Another eight people were in the second minibus. Always within the international rules of Gray Line, the driver, guide and organizer introduce themselves by name, and then before the start of the tour, Gray Line is introduced and clients are informed about the Covid vaccination of all employees and the course of the tour is further described.The guide had a microphone so that everyone could hear her. After an hour's journey by minibus, this tour is compiled on foot, because it is not possible to go with the minibus in the pedestrian zone. Information that this tour is walking is also on the Viator website. Due to the age of the clients, the guide leads the tour so that the clients can physically handle it and takes care of them all the time. After visiting Prague Castle there is a break for lunch and rest. In the afternoon on the boat there is also a rest. It is not possible to suggest more time by bus as guests would not be able to see many historical sights.
