Well just your luck, I'm from Beaufort SC. Yes there is a Beaufort GA and NC pronounced Bow-fort. SC is Bu-fort. For rental property, check with Hunting Island State Park, they have houses right on the beach. It's the big beach their and very nice. The houses are secluded, a little bit of a drive but worth the view. Fripp Island, Harbour Island are resort places, also located a little ways out on the island path but gorgeous and more tourist oriented. The drive out to these islands is about 12-15 miles, or no more than 20 minutes because it is 55mph and never to busy. Scenic all the way and beautiful. September is a great time to go too. In the city area their is not to much property to rent, but many hotels to choose from. Historic Downtown has a lot of B&B's, Beaufort Inn is so nice but $$$. They are all in the same neighborhood so go with a cheaper one because they have strict guidelines and are all pretty much the same. The Beaufort Chamber of Commerace has all the info.
Whatever info you need, just let me know, I know everything about the town, I love it there. I just moved within the last year away so I still have family and friends who can get any numbers or addresses you need.
Note*** Harbour Island's beach has no waves, it's on a small inlet, but you can walk so far out at low tide, nice shell findings, and wildlife. It has pools and clubhouse. Hunting Island is a mile further, has camping and fishing, the beach, and a lighthouse. Fripp Island is another 5 miles down and is the nicest of them all. A clubhouse or two, many pools, variety of rentals and the best beach in town. It is private so you don't have to worry about overcrowding. Their are alot of deer on Fripp Island so watch out. A few famous people live on Fripp too.
