You have landed and have a week or even two to spend on your holiday. You have to make your first stop to Oxford Street which became a whole day affair honestly with its line up of stores all in a row just for you to SPEND , SAVE, SHOP! Wherever you are , just hop on the tramp system ( London's version of our KTM) and get off a Oxford Circus station or Marble Arch.

You will be on either end to start your spree !
