Rachel and Jenny seated on the upper deck of an open-top double-decker tour bus.
We figured that if we only had one day to see London, the best bet would be the tour bus. It actually turned out pretty good, giving us exactly what we were looking for: Sightseeing with the ability to hop off for short periods and catch the next bus. Quite a nifty system they had there.
The weather was cold with a couple moments of intermittent misting rain, but it never rained hard enough to bother us. The worst thing was just that the seats on the top of the bus were damp. But even that went away quickly enough and we were able to enjoy the ride and the sights. At least as well as three people nearing two days without any decent sleep can enjoy it.
The trees you see in this photo basically whipped by, right at the top of the bus, but never quite hit the passengers. The buses travel these routes every day, so the trees keep getting trimmed by the windscreen at the front of the top deck.
