Plan ahead - London is busy so plan before you leave home or hotel. Up to date - new editions almost every year. Simplified - not maps but diagrams or 'quickmaps'. Not just a tube map - use the buses, tubes, trains and ferries as one network. All-on-one - everything is included. Colour spots - unique spot mapping links all the maps together. Wander - know about the walking areas where you don't need a map! Save money - travel in London is expensive so find walk routes or use the bus Speed-up - streets are conjested so head underground and pop-out back to the surface. Discreet - being pocket sized it goes with your mobile. Stylish and cool - find it on sale at the Tate Modern.
