Bus is way cheaper in London than the Tube. £1.75 per ride (unlimited transfers within an hour) and £5.25 max cap per day if you use your same contactless card. Underground and Overground can be faster but at £2.80/2.90 a ride in zones 1/2 (off/on peak) and daily cap of £8.90 its a bit pricier. If you have kids under 18, you can load an Oyster card with a youth visitor discount (50% off fares) but you have to get a TFL employee to do it at any station fare card sales point.

Benefit of the bus is that it lets you "see the sights" in Central London and you have the experience of riding on the double deckers.

The tube fare includes intercity trains (Thameslink, Avanti, Great Western etc) in the central zone. It can be way faster if you manage to time it right eg we took Thameslink from Farringdon to London Bridge which avoided transfers and was much faster.

Enjoy the trip!!
