How to calculate the hotel room rate?

Three days! One day is counted from the early morning of the first day to twelve o'clock on the first day, two days are counted from twelve o'clock on the first day to twelve o'clock on the second day, and three days are counted from twelve o'clock on the second day to the third morning. This is just the model and rules of the hotel. Of course, some hotels are more humanized and can be negotiated for two days. Hehe, good luck.
