Bears Den said he isn't camping.
We stay at a Hampton Inn in Mt. Pleasant right across the Arthur Ravenel Jr. Bridge. At this point you would be very close to Patriot's Point if interested in visiting the Yorktown. I believe there is a ferry that goes from that area to Fort Sumter as well. Driving into Charleston from there is not that big of a deal.
If money is no issue, try staying at Two Meeting Street Inn.
