I know its late, but for future reference theres a brand new 24-Hr Walmart supercenter just off 42 south of the 295 split. You'd take 295 south, then instead of getting on 76 and towards the Walt Whitman, you'd take 42 south (only about 2 miles) to the Deptford exit (12). The Walmart is right there on Clements Bridge road, east of 42. It'd be an easy drive for your daughter too, since its right near the end of 55.
Thanks Mike. That is good info.
