We visited Nashville in June. We stayed near The Opryland Hotel. Even if you don't stay there, it's worth a trip, it's quite a sight. The Opryland Mall is OK, but I come the land of malls, and found it just OK. Opryland Hotel reminded me of a Vegas type resort, without the gambling! We are not so into country music either. We did the Gen'l Jackson river boat, which was pretty good. Did the afternoon trip, so we saw downtown from the boat. We went to the GM Corvette Factory in Bowling Green KY - that was really interesting. Bowling Green is about an hour north of Nashville. Also did Lost River Caves in Bowling Green to finish our day there. They were smallish caves, but we were looking for something in the area. We went to Belle Mead plantation and enjoyed that as well. I did do some outlet shopping, if only I could remember the name..it was off the major highway that runs between Knoxville and Nashville. You can see it from the highway. I got some good deals at the Nike outlet and the Bath and Body Works Outlet.
Have a great trip
