We were in Nashville last year
Combined it with a family holiday - New Orleans, Memphis, Atlanta, Smoky Mountains, and a weekend at The Masters
Grand Ole Opry and Country Music Hall of Fame were excellent
Titans stadium tour is impressive as well
The city itself is spotless, with plenty places to drink and eat at reasonable prices
The Wildhorse Saloon offers an evening filled with fun, dance and grub for all the family - Make sure you check though, as they have a lot of private parties
We found it really nice to walk along the Mississippi Waterfront on an evening too
Not sure what you've got planned, or for how long however, doubt you'll be disappointed
Have a great time!
