lol, I think it will be a pain for trip to come and get you from the train station. Even when we get a lift to lincoln we get a bus to the UEA. Thats the way he comes into the city and it's a pain to drive all the way across it. Particularly on a sat. Poor little trip lol.
Get the 25 bus from Norwich train station. They run every 10 mins or so, takes about half an hour. I think sarah is getting it and it should be fairly clear when you are there. You will either go past a tesco metro and get off down that road or go closer to the UEA which should be pretty clear.
