A system and a method are disclosed for replacing a canceled accommodation for a guest user using reserved accommodations. In an embodiment, an accommodation management system retrieves information describing historical bookings and listings for accommodations in a region. The system determines common attributes of the listings and a historical cancelation rate of bookings. The system determines an amount of listings to reserve for a time period based on the historical cancelation rate and moves, from an available listing database to a reserved listing database, the amount of listings for the region, each listing including common attributes. The system sends an indication to each host user of the moved listings that the listing has become unavailable for the time period. The system receives an indication that a booking for a guest user has been canceled and books one of the listings in the reserved listing database for the guest user.
