Well after a bit of research, the pay per ride fare is £1.50 for DLR
only and £3.00 otherwise (thats to get from the central zone to even
the furthest extreme on the DLR). A day ticket will cost £7.20 for the
same service, but unlimited travel (within the zones), and a 3-day off
peak for all zones (except A-D) cost £18.90. Hope this is useful (NB

fun in London.
