A grand tour
If you only have a short time in London, make the most of it on a bus tour with The Original Tour (p. 33). The company’s 24-hour tour takes in all the major sights including Big Ben, Tower Bridge and The Shard, and also includes three walking tours and a hop-on, hop-off Thames river cruise. Its 48-hour option features a longer cruise to Greenwich. Since The Original Tour teamed up with Lebara Mobile, adult passengers can take advantage of a free SIM card – collect it from The Original Tour’s visitor centre by Trafalgar Square. Each card is preloaded with £1 credit for calls or data, so you can Instagram holiday snaps on the move.
