There's really no tipping culture in South Korea, says Katie Kin, a salesperson for the Korean American Travel Bureau in New York City, and it's not even expected of tourists. The exceptions include excursion guides, who get the standard $10 per person per day, and drivers, who get half that. Hotel porters should get the usual $1 per bag, says travel agent Cindy Yam. In other situations, "if you really love the service and you want to do something extra," you might tip, says Kin. Otherwise, you're off the hook.
