Use rail.ninja with caution
Chocked to see that the price for Seoul -> Busan tickets is twice the pice compared to when you buy them at the station. This is only disclosed when the purchase has been completed. Furthermore, it was not possible to choose seats and we of course got the worst seats in the train for premium price. Really regrets using rail.ninja. It gets two stars since the service works if you don’t care about price and seats, and just want to be sure io get from a to b.
