so F or H turn into its terminal?? or both??
btw, for D, what do you mean full view of Singapore River? i dun
think there are any service that are able to travel along the banks
of Singapore river....
Like in one direction, F leaves int A and joins H until H enters
int B. In the other direction, H leaves int B and joins F until F
enters int A.
Sorry identified wrongly, D can see Marina Bay, not Singapore
River. Btw with this in mind D should be the easiest to guess among
all the svcs here IMO, you may wanna start from D first.
