Nashville in late fall hits the sweet spot. The summer crowds clear out, Broadway honky-tonks actually have room to walk around, and hot chicken tastes better when there is a cool autumn breeze. Visiting mid-week keeps hotel rates far lower than Friday or Saturday nights.
A typical trip runs about $1400 once you cover lodging, flights, food, and music. Using a card with 0% intro APR for 15 months on purchases and balance transfers lets you break that total into manageable monthly payments instead of taking one big hit at once.
Remember that 0% interest is a deadline, not free money. If you still carry a balance after the 15 months end, the standard interest rate kicks in on whatever amount is left.
