What does the hotel mean by writing the bill early?

Hotel room rate includes breakfast for one person, and double breakfast room rate includes breakfast for two people. No breakfast means that breakfast is not included in your room rate.

Hotel reservation: the hotel stipulates that the check-in time is after 2 pm, and the check-in time for the next day is noon 12. Under normal circumstances, the check-in time is adjusted to 10 am, and the check-out time is adjusted to 2 pm, but it also depends on the situation. If you stay until 6 pm, in most cases, you will be charged half a day's room rate.
