Ah, hm, weekdays is a bit more difficult - I'd prefer to go by car because I just checked out train connections and rediscovered how criminally expensive Deutsche Bahn is compared to England (30 Euro one way - WTF? I could get from Durham to London for that price! although I did have a railcard in England, maybe that's the difference...), and during the week my mom will need the car to drive to work. So maybe it isn't that easy after all.
