For bros who are holding on to physical Horizon ferry open ticket, do note that if they are expiring soon, DO NOT throw them away YET. You can bring it to Horizon ferry counter at Harbourfront to extend its expiry date,hehehe...
Do however note that you will need to go there for extension before the open ticket expires.
Its PHYSICAL open ticket, and NOT promotional coupon/voucher/e-ticket.
For more enquiry, better to give them a call to double check. I just did,hehehe...and above were the information i gathered.
Always good to know that my ferry wont be going to the bin for now. And a small update is that Horizon only left with about 2 ferry trips a day,hehehe...
