Has anyone used one? I am staying in a B&B that is on the national rail in zone 4. Can an oyster card be used to get to it? Any advice would be helpful.
I have one that I use when I'm down in London. I'm not sure, but I think that Oystercards can only be used on London buses and the tube, plus a few train routes that cater to commuters.
