I want to know more about the hop on hop off Delhi bus. I have seen what the bus service offers, but what I want to know is that if I travel by car to the start point, I would not be brought back to the start point, would I? From what I have read the dropping and last point is different from the start point, does that mean we would have to make our way back to where our car is parked? Also, the start point is not very clear, the pickup points have been mentioned, but there is no clear mention of where the actual trip starts from so that no sightseeing spot is not missed. I would also like to know where I can purchase the tickets from?
