Yeah it's awful. I took it every day to school before I got a car. It's late, it's slow, its uncomfortable and it's really not that much cheaper. A day ticket for the bus in NI is £3.50, that's about £700 a year.(And this is for the bus, god knows how much if you take the train) Driving to school and back home costs me about £1 in petrol per day. £200 a year. I suppose there is insurance and stuff to consider but really I'd say driving is really not that much more expensive that the bus.
