I plan to come on hollidays in London. Can you tell me
how to go from Stansted Airport to Kings's Cross Station ?
what is the less expensive ?

The cheapest way would probably be the Terravision Airport Shuttle at
£7.00 single and £12.50 return. This will take you to Liverpool Street
station where you can catch a local bus or underground train to Kings
Cross.

Quicker would be to catch the Stansted Express (train) to Tottenham Hale
and change to the Victoria Line there.

You might like to have a look at Stansted's website which will lead you
to further information:

For 6 days of tourism in London, what is the best travelcard
to buy ? what is the price approximately ?

A 7-day Bus Pass will cost you £11 - this will take you all over
central London and the suburbs.
A 7-day Travelcard (Tube, DLR and bus) will cost between £18.50 (Zone 1
only) and £39.50 (Zones 1 - 6)

The Transport for London website can be found at:

Hope this helps
