Since I am covering the states in the 50 states I drove through more than stopped in, South Carolina also tends to fit that bill. When our son was little, we would send him down to his grandparents in Florida and then a week or two later leisurely drive down to pick him up or vice versa, drive him down and drop him off for a few weeks. This was a great way to combine both a family vacation and getaway kidless trip.
Back in 1998 on one of those trips, we stopped for a few nights in Charleston, South Carolina, which is definitely a city for romantic couples without kids. The horse drawn carriage is the only real way to see the city.
It is a city of old churches and gourmet restaurants. It seems that Poogan's Porch, the restaurant seen below, is still in business although they have painted the building since we were there.
In fact, it is the brightly colored Victorian era pastel "painted ladies" on Rainbow Row which are the signature feature of Charleston, although Forth Sumter is the draw fro Civil War buffs.
Fans of military history are drawn to The Citadel which has trained generations of southern gentleman.
Speaking of the Civil War, antebellum mansions like the one at Magnolia Plantation with its picturesque bridge is another tourist attraction.
Charleston and the South Carolina Low Country have a certain timeless charm which deserves revisiting.
