The orange ticket you mentioned, have to be purchased in Batam. No use to me unless *someone* can help me bring from batam to sg without significant markup and without having to go the end of the world to meet up for collection. *Wink* I also quite stingy one, you know..
So far, only Horizon Ferry tickets are not open ticket. Other e-tickets for traveling to Batam Center are open tickets, i.e. free to utilize them within a 2 months period
Anyway, I'm buying 1 way only. And, as you know, I've been buying e-ticket for more th a year plus, without issue. Hopefully this is including taxes and fuel surcharge. Maybe not "travel to Batam for free", but to use HBB paying only $30 is already a big savings. I'm contented liao.
