I've stayed here 3 or 4 times in the.past, the night before catching a flight out of Gimhae. This time, when I arrived early in the afternoon to check in, the receptionist said I had not paid to check in at the normal time - I had to wait until 9 pm. I would have to pay an additional 20K won (about $20) to check in now. I was travelling for work, so I paid - I'll be reimbursed anyway. I checked my reservation - it said check in was 3pm to midnight, but buried in the room details there was a note about not checking in before 9 pm. This never happened before, and the amount I paid online was about the same as the previous times. I have liked staying here, but next time I'll look at other options and read all the fine print. Buyer beware!
