Can't I book a hotel for that night after 12?

I can't. Flying Pig can't book the hotel after 12, because it was booked in the early morning after 12, so it can only be regarded as the room for the next day, not the room for the same day. Even after the next morning 12: 00, if you don't book a room in advance and then book it at this time, the hotel reservation system will default to the next day's room, and you can't stay in the early morning. So Flying Pig can't book a hotel that night after 12.
