I'm not quite new here, but this website I came across is. We're quite the Tioman regulars and we've found that lately more and more divers arrive at the Mersing jetty too late to catch their ferry, because it's full. The reason is that until recently you could only buy ferry tickets on the spot, i.e. at the Mersing jetty. In practice, this meant that a lot of Tioman-bound divers were forced to wait for the next ferry out, or even stay in Mersing overnight if they missed the last ferry for that day. A bit of a pain obviously, because last thing you want to do is miss your first few dives in Tioman. I reckon with Tioman Ferry Tickets, this should no longer be a problem. You can book your tickets by phone even before you're reached Mersing. No more missed ferry, no more missed dives, cool.
