I haven't been to Nashville but I know it's a great party town.
Austin would be a good city, also Savannah (you can drink on the street, which is cool)
I have been to all three. Savannah has to be the best of them with Nashville a close 2nd. Austin is cool and all but the homelessness is out of control. They are also trying to change the name due to racism from the city's namesake. 150 years ago Steven Austin said to not free slaves as they would become a problem if left to their own. If you go to Savannah PM me. I have a great VRBO right on River Street with a small terrace. We would have a nightcap and listen to the dude playing the sax. On our last night there I ran down to his tip jar and drooped a C note in and thanked him for 3 great night of music. Guy can play.
