AirAsia allows to prebook shuttle service between Senai Airport and Singapore. The details are here
The drop off points mentioned are Kranji MRT,Queen Street Bus terminal and Newton Circus bus stop. The rate per person is 6 MYR. Has anyone used the service? How is it? Worth using? Whether 6 MYR includes travel at both sides of borders. Kindly guide. I will be staying near Mustafa Center. Is the Queen Street terminal the nearest point?
