Tomorrow I have to go from Balham to Esher, then from Esher into zone 1
and then later back to Balham. As Esher is beyond zone 6 it would clearly
be impractical to get a Z1-6 paper travelcard (I have only a PAYG Oyster).
Does anyone have any suggestions as to the best way to manage the journey?

Many thanks,

Ian
