I just moved from there, and worked for Georgetown Hospital System for 15 years, mostly in the ED. Waccamaw is a great hospital. I would go back there tomorrow. Sometimes we would get pts down in the ED from up on rehab if they went bad (it's not considered a regular hospital floor, so pts who go bad can't go directly to another floor, from what I understood.) I had limited contact with the staff on the floor, but I heard nothing bad.
Waccamaw pays better than other facilities in the area, and they are building a new hospital in Georgetown soon. That gives you other options as well.
