Seoul in the spring is all about the Gwangjang Market and the cherry blossoms blooming along the Cheonggyecheon stream. You will spend your days moving between street food stalls and quiet temple paths, which is the best way to experience the city.
To make this happen without draining your savings, you can use the Citi Simplicity® Credit Card. It offers 0% for 18 months on purchases and balance transfers from date of account opening. This lets you spread the cost of your trip over time.
This intro window is a deadline, not a gift. If you still have a balance after the 18 months are up, the bank will start charging interest on whatever is left.
