One of my favorite cities in all of Asia is Seoul, South Korea. The place was a shock to my senses: 600-year-old villages intermingle with organic restaurants, street vendors and retail stores are swarmed by crowds and everything exists behind a mountainous backdrop.
With nearly 23 million residents, Seoul is also the third most populous city in the world. This means the city has a bit of everything and it is even more surprising how few U.S. travelers make it there. After spending five nights there, the incredible food and overall vibrance of the streets is what stuck in my head - and why I recommend you visit.
To get there, the best mile redemptions for U.S. residents are with the usual suspects (and their partners). 50,000 American, 70,000 Delta, or 70,000 United miles will get you a round-trip ticket in economy, while 100,000, 140,000 or 160,000, respectively, in business class. Expect $10 to $80 in booking fees.
