It's my first time staying in a hotel, and I can't understand the check-out rules. How to calculate this time?

If you stay in a room on the same day, you can stay directly in the morning as long as you have a clean room.

If not, you can normally check in after noon 12. Because the guests have already checked in, you can only stay if your aunt takes the time to do a good job of cleaning. If you don't do a good job of cleaning, the shopkeeper will not dare to live for you. )

Graduation costs money.

Check-out time is before noon the next day 12.
