Stayed in the air-conditioned room of the hotel for 10 days.

Hotels are profit-making units. Of course, I hope you can stay a little longer. So the hotel can stay for nine days. And if you agree to stay in the hotel for nine consecutive days, he will also give you a discount on the price. So if you choose a hotel, you can stay for 9 days in a row. Of course, a longer time is also possible! You are also very welcome to stay in the hotel for a long time.
