If you wish to use it for both, you have to provide a separate record for arrival and departure. A good option is near Avis or Hertz office in the arriving terminal beyond the custom control. You may withdraw money in local currency in the ATMs in the air-port. Most Taxis are limited to 4 people. Again, this is not a reservation service for taxi rides, just a tool you can use for your convenience to plan your trip arrangements.
