London, United Kingdom
Except for the fiasco at the originating bus station, the entire trip was fantastic. We lost time at the bus station due to an "over-selling" of tickets for the tour, and the tour guide had to find 4 individuals to "volunteer" to get off the bus. We lost 30 minutes while this happened.
3-star due only in part because of the weather. With continuous rain, both the visibility and atmosphere were dampened. Wish we could have seen more of the city, but windows on the bus DID NOT defog......
