Thanks Everyone for the comments and suggestions. They were all very helpful.
I made reservations at the ACOE park at J Percy Priest Lake. Looks like a great place and it was very full for the week we will be in Nashville. Will spend 3 nites in one space then move to another for the remaining two. Don't mind doing so and at $20/nite who can complain.
Pucketts Grocery and the Franklin Brewery are on our list of places to visit.
