MEET & GREAT is a service offered by the car rental company in case they do not have an office at the airport. In this case, the car rental agency does not provide the exact address of the office. MEET & GREAT means that one of the local car rental representatives will wait for you in the arrival hall holding a poster with your name. As soon as you meet the agent at the airport, he will lead you to the car or to the local office. If you do not find them or you do have any delay, please call the number from your confirmation voucher. Search car rental on https://www.jordancar.net/amman-car-rental.htm
