where they take you to the airport in your own car?
We have used them in the past and had no problems.
You drive to their lot - a driver gets in and takes you to the airport - they drop you off and then take your car to the parking lot.
No unloading luggage and transfering to a van - But - there must be room for the driver - this will not work if there are 4 of you in a 4 seat car!
