Having looked on various sites ( tfl ,BBC ,Getahead ) I now have a blinding headache . It seems to me that although the roads and underground will be busy ,the buses ( 36 ) seem to be running normally . But presumably the beach volley ball at Horseguards Parade and live screening at Hyde Park will have particular impact . TFL journey planner doesn't show increased travel time . What do people think ? Bus all the way ,allow ? 90 mins Underground from Victoria ? Please help ,there is so much info on line ,I'm not sure I'm nmaking sense of it ......
