Buying tickets on KKDay first and then getting a discount makes the price cheaper. The tickets are all assigned seats, which is very convenient and you don't have to fight for seats. The ship is clean and has no odor, and we arrived at Sado Port very quickly.
If you book a ferry ticket on KKday, you only need to show the QR code at the ticket office to redeem the ferry ticket at the local pier. It is very convenient.
