The cancelation of a booked reservation should ideally be before the last 24 hours, but Northwest Limousine Service is flexible with our loyal customers. We charge 50% of the cancelation fee if the reservation is canceled within the last 6 to 8 hours, depending on the circumstances. The best method would be to inquire about it from our customer care and by calling us at (855)-325-0777 or E-mail us at info@northwestlimony.com
