I fear Wapping is too far out for me. Have no way of returning home after a session. Even if I did, I would probably not get there due to increased navigational errorrs.
It's easy to get to Wapping. Either jubilee or district line east, then change to east london line and you're in Wapping. Even leaving at 11 you'll be back to Victoria by half past...
I'm not in London for a few weeks so doubt I can make this one.
