London travel advice

[weemidden]

In a nutshell - 4 days in London with DD9 and DS7. Cheapest/easiest way to travel - Oyster card (visitor/standard) or contactless card, and can kids travel free with either, do they need to register? Genuinely tried to read the London transport blurb, but in all honesty, I bow to the wisdom and speed of mumsnetters for information.

Your children do not need to pay anything or register, just have them follow you through the wider gate.
Oyster would be cheapest I think.

Oyster and contactless are the same price.

Children are free on buses, tubes and trams, they just go through with you.

Where do children just walk on to the bus?

Yes they are free with an oyster. Without an oyster they have to pay

Tantrums - children under 11 are free on buses and trams - they can travel alone. To go on the tube for free they need to be with an adult with an oystercard.

You might find it cheaper to get a weekly travelcard OP for 4 days - check out the price difference between that and 4x daily caps.
