The boat was packed, to the degree I actually felt unsafe. It was already noisy with people and then after finding somewhere to sit on deck at the stern, facing other people like on a tube train on some central wooden seats, an extremely loud tannoy commentary erupted on a nearby funnel, which for me ruined the entire thing. This continued the whole trip.
The tannoy advised that I may be filmed for promotional purposes, so at this point, and to escape the deafening noise, I went inside, found a seat and shut down, the tannoy less audible, and were it not for being in company I would have put my hood up to zone out completely. I could not wait for the ordeal to end, and when it did, as someone with walking issues, I was herded like cattle up a very steep ramp.
I would suggest providing a souvenir booklet to annotate the trip using photographs of the riversides and perhaps a broadcast people can tune into, if they wish, on their mobiles, so that others can enjoy a more peaceful river cruise, which this most certainly was not. The highlight for me was when the boat turned round, because I knew then we were at least halfway through.
