The time it takes for a hotel to get your booking information varies by the specific hotel and arrival date. In most cases, the hotel should receive the reservation information within twelve hours of the time you made your booking (except for nights and weekends when the hotel’s reservation department is closed). Please note that this doesn’t apply to bookings made for the same day.
There are certain reservations that are booked out of an allotment. These rooms are guaranteed and must be paid for when you check out of the hotel. In some cases the hotel won’t have your name on the reservation until approximately 24 hours before you arrive.
