The tour was advertised as a one-day trip, but it was actually made up of a number of parts, which made it disjointed. For a single traveller, the advantage of doing an organised tour is meeting people, but different people were on different bits of the trip. An hour and a half for lunch on the South Bank was fine, but advance notice would have been useful, as I had walked all around that area and had lunch there the day before. Those are the gripes out of the way. Overall, it was a good trip with interesting things to see, and it certainly gave me a flavour of the city and its surrounds. We saw a nice variety of things, too. The driver was particularly good and friendly.
