I am planning on going to Hilton Head, South Carolina for several days in early June. Since I am in the midst of a gold challenge, I want to fly AA even though they don't fly into Hilton Head. For someone who does not drive, what is my best option to get from ORD (or MDW) to Hilton Head? In other words, does anyone know the next closest airport and/or if there is a bus service (ie. greyhound) to the island? I know AA flys into Jacksonville but am not sure if this is my best option. Thanks
