You can always drive from the Embassy suites to the historic part. Out of the Emb suites front parking lot, Take a right onto Meeting St, Crossing Calhoun --drive straight to Market St. It will be on your left.
3-4 minutes tops. (Walking takes much longer.) Charleston Place Hotel will be on your right. Look for parking garage signs. (Ther is one at 200 Meeting St--on your left-)
If you find a place on the street to feed the meter- Parking will cost you some change. DO NOT LET THE METER RUN OUT. The meter reader will not be kind, even a couple of minutes late.
Take a lot of quarters.
If you need ideas for restaurants, let me know.
Oh yeah- be aware that Charleston has a ton of one way streets and can be confusing for a tourist.
Have fun in my Hometown. Wish I still lived there.
