I very much enjoyed the 3 hours spent with Chris exploring the historical highlights of Sydney city centre. Chris managed the large group of around 30 plus people very well and made sure everyone could hear what he was saying. He spoke clearly and had lots of interesting information to impart. Yes - you are expected to pay and I think most people did. However it is up to you. He puts in a fair amount of effort and is friendly and willing to interact with everyone. I would recommend this tour.
