Check out is a word that comes from English, it is a word that is usually used in the hotel sector to refer to the process by which, a person in particular, after having been staying in a hotel, at the time of leaving it, You must go to the counter or reception of the establishment or venue to cancel each and every one of the debts or pending accounts and deliver the keys to the previously reserved room; specifically the word check out is assigned to the process of "checking out a room or guest."
Therefore, check out is the moment when the time agreed upon at check-in or reservation expires, and the guest asks the receptionist for an account statement in order to review the charges on the account, whether for phone calls, mini-bar, viewing pay movies, etc. and once satisfied with the charges made, cancel the amount agreed on the invoice and then leave the hotel. It should be noted that hotels usually set a cut-off time for both registrations.
There are several types of check out, for example this is the scheduled check out, it is when it appears on the list of scheduled departures for the day, thus fulfilling the commitment established through the reservation made at the hotel; Another is unexpected check-out, quite the opposite to the previous one, it is when it is not foreseen in the list of departures for the day, this occurs at the request of the client; and finally, the delayed check out is one that, being on the list of scheduled departures for the day, does not occur at the time established by the hotel administration, so it can be extended beyond this time.
