I parked here to be close to the clt airport for a trip and found them online. I made my reservation ahead of time and prepaid. When I arrived at the lot, I simply showed my receipt on my phone and was told to park in any open spot. It is a big lot (covered parking is extra) and there were many cars. A shuttle then meets you and a friendly driver gives you a piece of yellow paper with your spot number. We were dropped off at the pre-arranged parking area at the airport and this is the same place you will come when you return from your trip. The shuttles circle frequently and we did wait long at all. On our way out, we were greeted with two cold bottles of water and the service was excellent. $6 a day is great and you are literally next to the long term lot of the CLT airport.
