Gets or sets the unique id of the Region where the customer wants to depart with Vehicle (rental start region).
This property is optional, but either DepartureRegionId or DepartureLocationId has to be set.
The ValidateRate - Method will perform a best-buy search(region based search), if this property is set by the caller. Therefore the property DepartureLocationId has to be handed over as '0', if a best-buy search(region based search) shall be applied.
