The bad thing about Nashville is the traffic. Be prepared to take a while to get anywhere.
Be sure to visit the Gaylord Opryland Hotel. People love the Rodizio Grill and Mere Bulls, both on the higher $ side. Demos' Restaurant is great and on the average $ side. Camino Real is really good, the closest one is 408 Sam Ridley Pkwy W Smyrna, TN 37167. If you are history buffs there is the Sam Davis home in Smyrna and the Battleground in Murfreesboro TN. For the 2 young kids there is the Discovery Center at Murfree Spring in Murfreesboro. There is a Demos' and Camino Real there also.
