A reservation confirmation is a document or message that verifies a booking made for services such as hotels, flights, or restaurants. It typically includes important details like the date, time, location, and any special requests. This confirmation serves as proof of the reservation and helps ensure that both the customer and the service provider are on the same page. Customers usually receive reservation confirmations via email, text, or through a mobile app. It's essential to review this information carefully to avoid any misunderstandings. If changes or cancellations are needed, the confirmation often provides instructions on how to proceed with modifications or cancellations.
