Was just there for a few days.
Don't know what your interests are, but---
Do not try to drive everywhere, parking is an issue. Park at the visitor's center and take a bus.
The buses are free, there are different routes.
There are buss tours, and carriage tours.
If history is an interest, sign up for a bus tour, there are several.
The tour to Ft. Sumter is recommended.
The market is interesting for shopping and food.
Hyman's seafood is really good. Get the low country she crap soup for sure.
Plantation tours are available.
Oh yeah, the Naval museum at Patriots Point too
