If many ppls are going together, car driving is better. Not many transportation can reach there. We took A bus to the Expo but found that the A Bus only arrive Expo, but not depart from Expo We need to take E Bus to Airport to change A Bus.....But the point was that, we took 1x mins to wait E Bus to Airport and then another 1x mins to wait A bus to go home..........very tiring after long hour queuing........
