Well, for cheaper bus charter fees, you can find any of the
private bus companies. They have a fleet of 4 - 5 step coaches and
they have storage space as well. IT comes at a good bargain for $80
for a 2-way trip. 1 way trips cost $40 and the coaches could sit 40
- 50 passengers excluding standing passengers.
SBST charges $100 for a 1-way trip for any rigid bus (including
Dennis Dart and Scania N113CRB) or $150 for 2-way or 4 hours.
If budget's your concern, you should try the private bus
companies. There's Heng Bus Company, JK59, Woodlands Transport,
West Point and much more.
