We didn't have to exchange our tickets two hours before the flight. However, you will be given a numbered ticket in the order you exchange your tickets, so if you want to board the ferry early, it's better to exchange your ticket early. Some people were told to change into swimsuits on the return ferry because it will be difficult to enter Malaysia. Even if you register your fingerprints when you leave Malaysia on the way there, you will need to register your MDAC again when you enter Malaysia on the return trip.
