London to Stansted (via Cambridge)

Hi all,

This coming Sunday I need to get from London to Stansted, however due to EW it is a bus transfer. Now I don't fancy getting a bus and I see I could travel Kings Cross - Cambridge (change) - Stansted by train.

I would assume a London Terminals - Stansted single ticket is not valid to travel via Cambridge? Can anyone confirm this? Going on the assumption that it isn't I would need a split ticket (@ Cambridge?).

Would would the fare be for this trip? 1 Adult and 1 Adult Priv.

Many thanks Guys for your help.

The Wanderer.
