I drive up there, but like your scenario it will be my parents taking me and they aren't confident about the roads in the area at the moment - gawd knows how we are going to get out the housing estate lol. No buses are running either, I have too much stuff to take on the train, which themselves are severely limited and jam-packed when they do arrive.
I suspect I may travel up on Monday instead, when everything has calmed down a bit. Hopefully the worst will be over by then. In some ways I prefer to stay in Kent for a couple more days, get to see tomorrow night's snow better than in Norfolk judging by the forecasts. 7cm at UEA, 16cm in my garden at the moment
