With a rush of blood to the head I bought tickets for the paralympics archery at Woolwich. I have to be there at 9, alone with two small children. It's now dawning on me that its going to be anightmare and I won't even be able to get on the trains with a pushchair at rush hour. I can either come from north London or stay with friends in Denmark Hill, but even there, the route planner suggests I go into London Bridge first. Does anyone have any tips on how to get there without being suffocated in a crowd? Please
