The hotel's check-in time indicates the time from which the hotel starts charging for the day. If anybody wants to occupy the hotel room before the hotel's check-in time, the hotel charges for one additional day and considers it as previous day stay. Most hotels, however, can accommodate a little buffer time request by the customers, without any additional charge, if one wishes to take the room before the check-in time. For the most cost-effective usage of hotel room occupancy, the customer should try to reach at about hotel's check-in time and leave or hand over the hotel room at about the hotel's check-out time, but it may not be always practical because the customer's arrival and departure time of flights may not align with the hotel check-in and check-out time and for other reasons. The primary aim of writing this book on this subject is to present the subject matter in a concise and an intelligible form, keeping in view the needs of the average student.
