Bused my Dad up from Augusta to Charlotte. Really no competition here so we were at their mercy. My Dad said he had a good trip and that they were nice to him as he needs handicap assistance. Station is relatively clean for a bus station. It IS confusing in there and it's not exactly obvious which line to stand in so that you catch the right bus. And you can't track where the bus is using a smartphone or computer.
But it was affordable but the schedule was somewhat inconvenient. He made it here and back safely so i guess that is what ultimately matters.
