For the conference in London, it is recommended to drive the Peugeot 407 saloon as it is more fuel efficient than the Ford Mondeo. The Premier Inn London Docklands is the closest and most convenient hotel at only a 5 minute walk from the conference center. Public transport is not needed since the hotel is walkable, but driving would allow flexibility. The trip involves traveling on Wednesday and returning on Saturday to make best use of time within the daily £100 expense limit, totaling £300 for expenses.
