Worth the drive if 1 wk? - Toronto to Wrightsville Beach, NC

Hello,

We are a family from Toronto, ON - our children are 19 and 13. The plan is to drive to Wrightsville Beach and stay there for 4 - 5 days. We have 7 days total - could extend to 8 max.

Could you please make recommendations for the road trip:

- is it doable to stop for one night on the drive there (and also 1 night for the drive back)? = 4 days on the road? That would leave only 4 days at our destination...

- recommended places to stop for the night - enough time to visit - ex. Washington?

- suggestions and best route would be much appreciated!!
