Do i need always a passport to book a room in hotel for one night ? sorry for my english

If you are Thai you do not need a passport.

If you are a tourist you should have a passport anyway.

Hotels are supposed to know who is residing in their hotels. I want hotels to know who is checking in because I do not want an ax murderer next door to me! If something is stolen from a hotel room I think the police would like to know who was residing in the hotel. Doesn't that make sense?

Why would you not have a passport if you are a tourist in Thailand?
