A: One day, one night on the 2nd.

Question 3: What are the general rules? Please answer the above two questions before answering this question, otherwise I'm afraid I don't understand: p Thank you first!

A: I stayed for a few nights, 1 checked in, and checked out at 2 am on the 3rd and 6 am, but the check-out time was particular. If you check out after 12 o'clock or 1 o'clock in the afternoon, some hotels will charge half a day's room charge, because you occupy the room, which may affect the people behind you, but different hotel policies are different.
