My daughter and I will be attending an envent a UNC Chapel Hill. I have made reservations at the Sheraton Chapel Hill. I understand the Shearton has a shuttle to and from town, which is very convenient for us. However, does anyone know if they have a shuttle from the aiport? If not, can someone recommend a reasonable transport service. We will be arriving around 9:00 p.m. I prefer not to rent a car as we won't be there too long.
