They probably charge u the same rate to any 2 destinations. That is the fare per vehicle & they will try to fetch/alight passengers on the way too.. i normally stay in Nipah but often goes to Pasir Bogak..
I always go alone & pay RM10 for all this short distances..
On holiday weekends , you definitely have to share with others.. barely enough pink taxis with so many travellers coming out non stop from the cheap RM10 ferries..
If u have a motorbike license it's best to rent a motorbike at the jetty & u can go anywhere u want to..
