Any ideas on transportation to columbia?

<p>My daughter a student at University of South Carolina will be in Charleston next week and will need to find transportation back to Columbia. Unfortunately the function she is attending will not end to at least 7 pm. The next greyhound bus going to Columbia leaves at 10pm and arrives in Columbia after midnight. I am just not comfortable with that. Anyone have any ideas on how to get her back safely? Maybe a private livery service you might have used in the past? I am thinking she may need to stay overnite and take the bus back in the morning. No planes go from Charleston to Columbia... she would have to fly first to Charlotte and then to Columbia ...doesn't make sense. Any ideas would be appreciated.</p>
