What does the travel agency mean by staying in a hotel for one night, and what does it mean that day?

The travel agency said that staying in the hotel for one night means staying for one day and paying the room fee for one day.

Usually check in in the afternoon of the same day and check out before noon 12 the next day, which is the room rate for one day.

Because the waiter has to clean the room in the morning, the check-in time is usually after 1 pm. If the hotel has cleaned the room, you can check in before noon.

However, if you check in in the morning (ask the hotel for the specific time), you may have to add half a day's room rate. Similarly, if the check-out time of the next day is later than noon 12 and earlier than 18, the room rate will be increased for half a day.
