I'd be grateful if someone could explain to me please how I can get from London Liverpool Street to Heathrow Terminal 5.
Is there an underground connection between the two?
Why is Heathrow Express so expensive? Is it the only possible way of getting to terminal 5?
I'm really confused about this, and I don't usually have problems arranging trips.
Will be travelling with DD who will be just about 4, in case this is relevant. My main interest is to keep costs down and to make the journey as easy as possible (obviously).
Would be very grateful to hear from someone who has done this themselves.
