South Korea is a paradise for food lovers, from the endless street food stalls of Gwangjang Market to the intricate temple cuisine of Seoul. Traveling during the shoulder season, typically spring or autumn, helps you avoid the worst crowds while scoring better flight prices and enjoying perfect weather for eating your way through the city.
A trip like this usually runs around $3000. To manage that cost, you can use the Citi Simplicity® Credit Card, which offers 0% for 18 months on purchases and balance transfers from date of account opening.
Remember that the 18-month window is a deadline, not free money. If you have a balance remaining after the 18 months are up, you will start paying interest on the remaining amount at the standard rate.
