Private car hire 300,000 IDR
Fast boat transport 350,000 IDR
Once I got off the plane it was very easy to make the arrangements. I had barely left customs when a man approached me that worked for the transport company. They have a shop set up in the area before you exit the airport. I told him where I needed to go and he made arrangements for the transport by car. The driver then took me to where I needed to buy the ticket for the fast boat. Easy peasy.
All of 30 minutes to get to the island. I had a great nap.
