When do hotels usually reduce prices that day?

At night 10 during the day, fewer and fewer people are staying in hotels, and hotel merchants are anxious, and then they need to increase the discount of hotel prices, so as to grab the last wave of customers at night. It will be cheaper to book hotels after 10. Also, it is the cheapest to book a hotel from 6 pm to 10 in a day, because the hotel will adjust the price according to the number of rooms available. In addition, the price of booking from Monday to Thursday is cheaper than that of booking on Saturday and Sunday. In the off-season, the later the booking time, the lower the room price, because the more rooms left on the day, the hotel will adjust the occupancy rate by reducing the price.
