Seoul hits different when you are wandering through Namdaemun Market at midnight, eating hotteok straight off the griddle, or waking up early to catch the quiet at Gyeongbokgung Palace. November brings crisp autumn air and changing leaves, while March brings the start of the spring thaw and fewer crowds. Either month gives you the best mix of street food, ancient temples, and neon-lit alleys without the crushing summer humidity.
A typical trip runs about $2,800 for flights, a solid place to stay, and food, which is a lot to drop all at once. If you want to break that cost down into smaller chunks, you can use the Discover it® Cash Back card. It gives you 0% intro APR for 15 months on purchases and balance transfers, meaning you can spread your payments out over time without paying interest while you chip away at the total.
Remember that the intro window is a strict deadline, not free money. If you still carry a balance when the 15 months are up, interest will kick in on whatever is left over.
