I would drive from NJ to Richmond, VA. Stay on the South side in a Hampton Hotel. I would drive from Richmond, VA to Savannah, GA. Stay in a Hampton Inn. From Savannah I would drive to Jacksonville, Florida and take I-10W to Biloxi, Mississippi. I would stay at Beau Rivage Casino&Hotel. It is 75 minutes from New Orleans. It is best to enter New Orleans in the daytime. Stay at the Hampton Inn near the Cruise Ships.
