The other alternative is two Oyster cards. Swap cards at OSIs.


Which will end up costing more, up to double the cap for using just a
single Oystercard.

Personally, now Oyster is available everywhere within the zones, I can
see no reason why One Day Travelcards can't be sold on Oyster,
especially as there should be a spare 'slot' if the card only has PAYG
on it.
