A traveler secures a hotel room, restaurant table, or transport seat for a future date by providing details and often a deposit or guarantee. That arrangement is a reservation. It reduces uncertainty for both guest and provider.

Reservations may be free to cancel until a deadline or become non-refundable immediately. Confirmation numbers serve as proof. Overbooking and no-shows create tension in the system; policies try to balance occupancy with fairness. Digital confirmations have largely replaced paper vouchers.

During busy periods a reservation is the difference between staying where planned and scrambling for alternatives. Providers use reservation data to forecast staffing and inventory. For travelers, keeping records of all reservations prevents confusion at arrival.

A confirmed reservation turns a preferred option into a planned fact.
