Off to Selhurst Park on Sunday.
The usual arrangement when attending matches at that London is to park at the end of the Jubilee line (Canons Park) and tube it to the venue. On this occasion (unless DiS knows better) I will need to switch to overground at London Bridge to get to Crystal Palace.
Q. Will I need to buy a separate ticket for the overground or can I buy tickets at Canons Park to cover the whole journey?
