I’ve gone every year for the last 35 years with no issues. Do make sure of “situational awareness”, and SC does CCW reciprocity with my state. Also aware of “events” that I feel uncomfortable with (Like the various Biker weeks or spring break). Otherwise we love going there for vacations....
Being from NC, we always went to North Myrtle. MB was off-limits as it was full of Yankees and Canucks.
