Once I get to London from heathrow (using an Oyster card). I will be in London for 9 days, taking the tube and bus to many locations within zone 1-2. But I also want to visit Bletchley Park and Kew Gardens, which I see have 2 for 1 admission deals.
I am going to purchase a 7 day travel card from Euston Railway Station in order to take advantage of the 2 for 1 deals for those two locations. I know that I will have to bring a passport photo to affix to the card.
So what are practical details to use the card, once I have the card?
Do I just board the train at Euston Station to Bletchley park and sit anywhere? Or do I have to get a reserved seat ticket from the ticket window after showing my travel card? How do I validate the card in order to board the train?
Do I have to validate this 7 day travel ticket at some machine at Euston Station and (on the return - Bletchley station) before I enter the train? Do I have tap out at a ticket machine once I arrive at the destination? (This is for the railway card. I know I have to tap in and out for Oyster card.)
Same questions when I travel from Waterloo Station to Kew Bridge Rail station?
These two destinations are the only ones that will be outside Zone 1-2. Should I just get a 7 day travel card for zones 1-2 and then just pay the supplement at the ticket window for zones 6? Or should I just pay for a 7 day travel ticket for all zones?
As for using the7 day railway card on the Tube and Bus. Its a paper card. how do I validate it when using the Tube. How do I validate it when using the Bus?
Thanks for any insight and information from you London transportation users!
