Are you flying in? We stayed at the airport Drury Inn in April for a night before getting a rental car. Their shuttle is free and can use anytime. We got in at 11pm and they had a ride for us in less than 10 minutes. The airport was really clean and in good shape, my wife and kid enjoyed the pool. The breakfast area was small but the continental breakfast was good. I believe they also serve lunch and/or dinner and it might be free, I forget, but my wife loves it.
the airport is undergoing major renovations, so it’s a bit of a hike to the shuttle pickup, but it’s the same area for other pickup and rental car, just be prepared.
there’s lots to see and do in Nashville but it’s really spread out, so not having a car puts you at a disadvantage. First time in Nashville though, it’s always worthwhile to check out The grand Old Opry house. Check out their site for tours:

It’s also right next to the Opry Mills mall so once your tour is done or before it begins, you can grab some food, etc.
This location is also just a short distance from the Drury, about 15 minute drive.
You could also check out Music Row. I’m not as familiar with it, but I believe there are lots of music bars and different recording sites around, maybe research the location if it sounds interesting to you and see what you might want to do. It’s also really close to one of my wife’s favorite spots in Nashville, the Parthenon building. It’s an exact replica of the Greek Parthenon. We just walked the perimeter on our last trip, I think the inside didn’t open until the afternoon.
A unique restaurant near music row that I would recommend is called Biscuit Love. They’re a breakfast place, so they close early. My wife’s cousin is a manager of the Franklin location, so slightly biased, but the food is amazing.
here’s directions from Biscuit Love to Music Row. Centennial park on the far left is where the Parthenon sits. The Parthenon is about 2 miles from Biscuit Love, so you could theoretically take an Uber to one location and walk between. I can’t attest to whether this is safe or not, which is why I say theoretically.
thats about all I have for now. Enjoy your trip!
