I didn't look but someone else mentioned your from ny. Rates are going to be lower here. Obviously it depends on you but they can be anywhere from 100-300 on average. I see visiting girls asking more, Idk how well they do. I have seen some complaints from others abut touring here but it seems in general people like it. I'd it was me Id make it a vacation that funds itself.  

This area isn't that big, I'm on one end and I have people that come from the other end so you really can stay just about anywhere. If you want central, North Charleston, preferably by the airport and tanager outlets, it can be a bit ghetto other areas. If you want to be more touristy, downtown or one of the beaches (folly or isle of palms) Parking can be an issue downtown.
