Why advance booking helps
Booking ahead gives an operator time to plan drivers and vehicles around your pickup time, and usually locks in a fixed fare rather than a rate that could rise closer to the day. Popular slots such as early morning departures, Friday and Sunday returns, and school holiday periods get booked up first, so leaving it late reduces your choice of vehicle and pickup time.
