How to calculate the room rate from 9: 00 to night 10?

The room rate for 1 day and a half is from 8: 00 am to noon 12, and from noon 12 to afternoon 10 is 1 day. Hotel room rate is charged by room/night. Generally speaking, it is from 14 in the afternoon to 65438 at noon the next day. Check-in before 7: 00 am until noon 12 counts as one day, and 9: 00 can count as half a day, but some hotels don't have such a calculation method. It usually takes four hours to rent an hourly room, and no matter which hotel is from noon 12 to afternoon 10, it is a day. It is the least worthwhile for you to stay in a hotel during this period. .....
