When is the latest check-out time on the second day after checking into the hotel at 0: 00 pm?

There are no hard and fast industry rules. Generally, you can stay after 4 pm until the check-out time at noon the day after tomorrow. But all hotels didn't check in until after 0: 00, and they must have stayed until noon today 12 or 1, depending on the check-out time of the hotel the next day. You can't enjoy any discount at this time.
