I parked my car here with the recommendation from the charlotte airport site. They claimed that the shuttle was on demand but it really seemed to run only every 30 mins. When i landed today i called at 310 and was told the shuttle would pick me up at 330. 330 came and went and no shuttle. I tried to call back for about 20 mins and no one answered the phone. I was about to just take a cab and the shuttle showed up at 4:00. The shuttle driver claimed he was never told about a 330 pickup. I wouldn't recommend at all parking your car there for the airport.
