I have an upcoming meeting in Seoul and would like a recommendation from people in the know. I will be staying in Seoul for 3 days in December and attending a meeting at the Shilla Seoul. I can either stay there or at the JW Marriott Dongdaemun at about the same price. I am Bonvoy Titanium, and I also signed up for Leaders Club Sterling through Amex Plat if it could be useful.
