I spent a lot of time comparing the seven various Delhi day tours listed on Viator. This one seemed the most clear and comprehensive -- on paper. Happily, in practice, it was also quite good.
The guide Mr. Singh and driver arrived early and were waiting for me a 9:00 in the lobby. Plus, a boss from the company joined them to ensure that all was well.
The guide was knowledgeable and receptive about squeezing in two extra destinations feasible since it was Sunday and traffic was not so heavy. He was also good about giving the right amount of information balanced not too little and not too much boring overkill. He also had a depth of knowledge to draw on to answer any questions.
The official tour does not include a set lunch but they let you do that as you wish. I wanted caffeine and hit Starbucks when I grabbed a small sandwich.
I was quite please with this city tour. My main tip is to avoid the heavy traffic and go on a Sunday if you can.
The Guide and the driver were very forthcoming and took me to all the promised places, while providing the adequate amount of history to each location. Altough I ended buying some things at an emporium, the visit to this shop was not really necessary. Apart from that everything else was tip-top, everyone very professional and attentive.
