Charleston in late autumn hits the sweet spot. The oppressive summer humidity breaks, the cobblestone streets cool down, and dining tables at top Lowcountry spots are easier to claim if you plan ahead.
A solid three-day itinerary running about $1,400 for stays, flights, and meals can be split up over time instead of draining your checking account at once. Using a card with 0% for 18 months on purchases and balance transfers from date of account opening lets you spread the cost into manageable monthly payments.
A zero-percent promo window is a payment tool with a firm deadline, not free money. If you carry a balance past the 18 months, interest will apply to whatever balance remains, making your weekend trip much more expensive.
