I'm wondering if it's necessary to rent a car on an unpcoming visit to Charleston. I'm coming in early July for a 4-day trip with my husband for our anniversary. It will be our first time visiting Charleston. Right now, I'm thinking we'll be staying at a hotel in the historic district (nothing booked just yet). But I'm interested in visiting the plantations, touring Fort Sumter, downtown Charleston, and possibly even the beaches if time allows. Any input would be greatly appreciated!!
