Road Trip! need ideas, terrible planner?

My daughter's 16 and for her spring break i want to take her for a little mother daughter road trip. we live in central NJ and she has 2 weeks starting in the beginning of march. I've been looking in traveling books, but i am absolutely hopeless! i was thinking about going down to Delaware through baltimore virginia NC and SC then stopping in Savannah GA. I need a lot of input- like where to stop and stay and eat! also, will it be too much for 2 weeks? it needs to be really fun, because my little rebel teen is hard to please! we have a terrible relationship so i hope this trip will make her happier. she loves nature and cute small towns will probably be a plus.|||Make sure you go on the Chesabee Bay Bridge going into Virginia. If she has never been on the bridge before she will love it. You can take Rt 13 strait through Delaware and Maryland to the Chesabee Bay Bridge. Stop at the half way point grab lunch and look out at the water. If you eat seafood the crabs are great.|||bring some food money something to do like books, buy a gps and visit the capital and maybe u can book a tour in savannah by horse and buggy
