Any suggestions for a stop between Philly & Charleston, SC?

We're heading down in March and haven't decided on a place to stop on the way down. I'm thinking somewhere to stay 1-2 days in mid-March. On the way back up we're thinking of stopping in Charolette & along the BRP in VA.

How far from PA do you want to stop ?? Your in central PA , correct? So I assume your doing 81-77-26 ?? We stayed at Endless caverns in VA... just off 81.. we had a GREAT time , the kids were about the age of yours at the time and there was a ton to do!
