I stayed at the Mt. Pleasant KOA when I visited. One big advantage - you don't have to cross the Ravenel Bridge which is very busy in the early evening. And if I had seen the KOA sign, I wouldn't have had to cross the bridge in my 'C', pulling a Jeep Wrangler 4 down. Lots of traffic and no way to back up. I finally found a gas station that I could pull thru to turn around. Charleston is a lot more fun to visit driving just the Jeep. And you're also on the same side of the Cooper river as Patriot's Point. Several WWII Navy ships that have been turned into museums. I extended my stay for a full week at the KOA.
