Nashville is all about hot chicken, honky-tonks on Broadway, and catching live music in tiny bars where the people on stage might be tomorrow's biggest stars. You want to aim for late spring or early fall to get the best weather without melting in the humidity. Most importantly, check the city calendar before you book so you do not accidentally land during CMA Fest or a massive stadium weekend when hotel prices double.
A typical trip runs about $1200 for flights, a central place to stay, and food. When you are looking at how to manage that chunk of cash, you can use the Citi Simplicity® Credit Card, which gives you 0% for 18 months on purchases and balance transfers from date of account opening to spread out the cost.
That 0% window is a strict deadline, not free money, so make sure you map out your payments. If any part of that $1200 balance is still sitting there when the 18 months run out, standard interest charges will kick in on whatever is left.
