If you book in advance, its cheaper and you're guaranteed a seat. Which is the point of booking in advance. Bus is £3.70 for unlimited journeys (w00t).. I dont understand the whole cab malarky, as the brand new first buses are great and fast enough . I dont understand the stopping thing, why would you want to stop a journey? .People being useless and unorganised is a factor with people missing trains. Plan the journey ahead and you're fine :PBut I'm a train fanboy .
