We will be at FF Nashville the week before you are, so I have been doing a little checking.
The Grand Old Opry has a Star Spangled Tribute on the 4th. Shows at 6pm and 9pm. The tickets can be had through ticketmaster, but they are cheaper through FF. I believe that they said all tickets are $32/adult, $27/child. This is either main floor or balcony. That is a substantial discount from the $46.50 main floor through ticketmaster (adult/child same price). The person I spoke with said that for the Tuesday night shows, no need to buy early, but for Saturday, might want to call ahead. I would call ahead if you want the 4th.
The General Jackson has a special right now, (excluding 4th) save $20/adult up to 6. Code is GJ20. Number to call is 615-458-3900. These are the dinner and show tickets. They also offer upper deck music and buffet, or just music. The website has different deals offered, including 2 free kids' tickets with each adult, but it is for upper deck, music only. Their website is

We did the General Jackson Captain's table on our honeymoon and my husband was coerced onto the stage for the highlight (for hilarity anyway) of our trip. Now with 2 children we will not be paying for the dinner and show. We may do the outer-deck buffet, though.
Another suggestion that I have is for New Orlean's Manor. It is a restaraunt near the airport that is as beautiful as it is delicious. It is an all you can eat seafood buffet, set in an old New Orlean's style mansion. You can eat in the drawing room, parlor, or upstairs rooms. The food is set in the foyer (if I remember right- it's been 11 years). They serve prime rib, ribs, & chicken primavera in addition to the seafood. The buffet includes king and snow crab legs, but lobster is extra. They bring frog legs and oysters rockerfeller directly to your table. Coffee, tea or milk is included as well as dessert. The cost is $34.50/adult. $1.50/year kids 3-12 (I think those are the ages). They are open Tues- Sat 5p-9p. The food is superb!

Taking kids? Their is a giant bug exhibit at the Adventure Science Center featuring dinosaur size recreations along with the real things.
The original "Old Glory" American flag will be in Nashville for the first time in 100 years. That is at the Tenn state museum.
There is a "scent" art exhibit (scents as art as I understand it?) at the Art and Invention Gallery.
Pulitzer prize photos (over 180 I believe), and an Egyptian relics exhibit at the First Center for Visual Arts.
There is also a Ray Charles tribute exhibit at the Country Music Hall of Fame.
Ok, that is all I have right now, my hands are tired, and you are probably bored to tears. Let me know if you would like adresses or phone numbers for any of the above.
