How do hotels book rooms for several days at a time?

Do you want to book on the mobile phone software or directly in the hotel lobby? If it is on the mobile phone software, then find the hotel you want to book, choose the check-in time and check-out time after entering, and fill it out after a few days of check-in, that's all. If you make a reservation in the hotel lobby, you can tell the front desk how many days you will stay, and they will ask you to pay the corresponding deposit. It's convenient to check out when you leave.
