Top tip - park out of the centre to avoid the worst. I've used the Q Park at Regents Park a few times to help with a fast(er) getaway. Unless you can bail from the office early you still have to factor the time taken to get there, of course. The St Pancras car park isn't bad, either.Would love to convoy there from central
I'll ask tomorrow if they don't mind me using a couple of hours leave to get out early.
I am in Clerkenwell so not too far. If not I'll be leaving at 5.30 with the rest of the mugs
