How to book a hotel for two people to visit Jeju Island? Should I write two names on the hotel reservation form?

You can go to Ctrip or find a travel agency to book, and it is best to write down all the names, because Jeju Island should show its confirmation letter of booking a local hotel and a round-trip ticket to Jeju Island when it passes the border inspection, so as to avoid unnecessary trouble. Last time I went, I made a reservation with the local Coke Jeju Island self-service travel agency. It's a sea view room in Dragon Head Rock. You can consult them. If it helps you, please adopt it. Thank you!
