Summer (July and August) is also popular due to school holidays and various events, but it can be crowded and more expensive. Winter (November to February) offers fewer tourists and festive holiday decorations, but it can be cold and wet.

The Oyster card or a contactless payment card can be used for convenient and cost-effective travel across all modes of transport. Taxis and ride-sharing services like Uber are also available.
