What term is used for a customer with a reservation who fails to show up at a hotel?

The term used for a customer with a reservation who fails to show up at a hotel is "no-show." This term specifically refers to a guest who does not arrive for their booked stay, resulting in the hotel having an empty room that could have been sold to another guest. No-shows can significantly impact hotel revenue and can lead to operational challenges, as the hotel has to manage bookings and guest expectations.

In contrast, late check-out refers to a situation where a guest is allowed to remain in their room beyond the standard check-out time, which is a service most hotels can provide for customers upon request. Overbooking refers to the strategy where hotels sell more reservations than there are available rooms, anticipating a certain percentage of no-shows, to maximize revenue. A walk-in is a guest who arrives at a hotel without a prior reservation. Each of these terms has a distinct meaning in the hospitality industry, making "no-show" the correct answer for a customer who doesn't arrive as planned.
