Initially I paid for the Seaworld express ferries, same price outbound and inbound. Outbound to Jeju was a great experience, however for the inbound we were informed that there will be no ferry and there is an alternative Hanil Express which we accepted because it was on the same day.
No one told us that Hanil express was so much limited in services and quality, there was no restraurant options and we were starving entire trip. Hanil also seems cheaper in price than Seaworld which means we overpaid for what we were provided on our way back.
I would like to get a partial refund for this inconvenience.
