I know that over the years, the likes of Jamie Booth have come through the edge of east London and used the Woolwich free ferry. Jamie once said,"Its was like going on holiday!"
when coming home from work (M1) I use the M25 go round the east side ove the Dartford Crossing (£1 each way for cars/more for caravans) and come off at J4. It is 15 minutes from the M25 and fairy direct.
What time were you thinking of travelling/arriving and maybe I can help. I spend most days on the M1 and M25...
