I will be in London Sept 24-30. I have read many posts here about travelcards and Oystercards, as well as the RS book and the London transportation website. I am still confused about what I need.
I arrive by train (EUS) and will spend three nights in a hostel in Greenwich (London central is booked solid for the weekend). I assume I will use quite a bit of transport to get around.
Then I move to a hostel on Oxford Street for four nights (eventually leaving for LHR). I do not know how much I will use public transportation. A lot depends on the weather.
I have searched but cannot find a Zone map. Where is it? Is Greenwich within Zones 1-2?
If I buy an Oystercard, I assume I will hit the daily cap on the first three days from Greenwich. If I don't hit the daily cap on the remaining days (say I just use 2GBP of buses, etc) I can have the balance on my card refunded upon departure, correct?
If this is all correct, then doesn't an Oystercard make more sense than a TravelCard? Especially if there are days when I wander further afield than Zones 1 and 2?
