Hotell nær O2 Arena i London

Like an alien ship that’s plonked itself on the banks of the Thames, the striking form of the O2 is unique. A giant marquee, it’s seen Coldplay, Pink Floyd, Madonna and many others take to the stage, while the IMAX’s giant cinema screen roars over audiences. Braver visitors can don a harness and scale the dome’s heights – the views over East London are well worth the climb.
