This weekend (Saturday) I will be travelling from Cambridge to Canons Park underground and back
Normally when going through London I get the greater Anglia travelcard which obviously is unlimited tube journeys but this weekend I notice Greater Anglia are running bus replacement service part of the route which I don't really to be doing so I will get the train from Cambridge to Kings Cross £9.40 return with Railcard discount, then I will travel by tube to Canons Park (changing lines at Wembley Park) this is the first time I would have ever tapped in and out, am I right in thinking I only need to tap in at Kings Cross and out at Canons Park and same for the return journey, and I don't need to tap anything at Wembley Park when changing lines?
I would rather not make a mistake and be charged anymore than I need to pay
