For example, when do I check in at 5: 30 in the morning and check out?

Generally speaking, the normal check-in time of the hotel is 12 o'clock on the same day (or 14 o'clock), and check out before 12 o'clock the next day (or 14 o'clock), and collect the full-day rent. Check out before 8: 00 the next day/kloc-0, plus half a day's rent. Judging from the hotel system charges, you can check in normally after 6 am.

Some hotels will stipulate that check-in before 6: 00 a.m. is a whole day, and charge full-day rent until 12 o'clock that day; There are also some regulations that check in after 3 am (or 4 am), check out at noon 12, and charge half a day's rent.

According to the regulations of each hotel, the charging standard is different, so you should ask clearly when C/I.

As for what you said, check in at 5: 30 in the morning. I suggest you take a nap in the lobby for half an hour and go through the formalities at six. Or, if you are attractive, you can discuss with the front desk and let them check in in the system after 6 o'clock.
