Check out after the hotel 12.

According to the regulations, 12 from noon to noon the next day 12 is 1 day. Noon 12 to 18:00 is half a day. After 18:00, it will be regarded as overnight. This hotel mainly sells overnight rooms. So check in with someone else in the early morning before you check in at 65433 noon. It's 1 day, until noon 12. Because your room is only for one night, whether you check in after noon 12 or in the early morning, it is 1 night.

So to answer your question, 1 is 1 day; Question 2. Calculate 1.5 days; Question 3, count 2 days.

Of course, if you check in after 6:30, you can negotiate with the hotel and take noon 12 as your check-in time. Some hotels can appropriately advance the check-in settlement time at noon 12 for the occupancy rate. Specific hotel regulations shall prevail.
