Online information and delivery service were excellent. Pick up service from the airport could be improved by making return pick up locations explicit. I was told return service was ground level, below, when dropped off, but did not understand it would be from only two locations. When I called for pick up, because of loud noises in area, communication was difficult. I called a second time after seeing the driver pass by. The driver picked us up from the location I gave him, and he explained that pick up was from two other points. A hand-out card with instructions, providing telephone number and two designated locations, given at time of registration, would improve service. Knowing the two pick up locations is important.
