Hello,Mr.Hughes

Most of the time, you need to chart a van or take a taxi. If you can have other people heading for the same direction, you can share the cost then. For a first timer, it is a little hard to get to know where to take a bus and which bus to take. As most of the time, the buses do not have them as departure station or arrival station. Buses just pass by.
