TERRIBLE Experience. Called them upon arrival, was told to go to "Door 1" on Departure Level; I found that there was no such door. Called back, they corrected to "Door B" on Departure Level. Called 20 minutes later, they changed it to "Door D" on Departure Level. Called TWICE MORE, 20 minutes apart. Each time I repeated back to them what they had told me and they confirmed. On my last call, I was finally told that their driver was waiting at Door D on ARRIVAL level!! Each call required me to walk a far distance and a flight of stairs from where they told me to wait to where there was a solitary public telephone, and it took them a very, very long time to actually answer every call. Gave 1 star because, once I found the driver, the trip was quick and uneventful. But their total disorganization, and having to WAIT MUCH MORE THAN AN HOUR made this a really bad experience.
