But I haven't studied the attention points of entering London, such as whether to pay the congestion charge, how to pay, and whether parking is consistent with other places ?

We 8 people, including 2 children, all dragged luggage to the airport to rent a car.

It depends on the specific location. You need to pay for the downtown area. It's recommended to pay in advance, but I'm not quite sure about the details.

The core area is only free on weekends and holidays. Most car rental companies have a map of the core area. The core area not only charges fees, but also has temporary traffic restrictions at any time. In order to experience, it is not recommended to drive around scenic spots.

Best to return the car at the airport now, it's very convenient to enter the London subway. I saw some foreigners with a lot of luggage also taking the subway. It's very inconvenient to drive into the city, put down the luggage and come out. There's really no need for it.
