For the third straight year, Seoul has ranked fifth in the world for number of international conferences hosted.
Its airport is the busiest in Asia.
Hotels are bursting to capacity.
An increasing number of business travelers is arriving each month to South Korea's capital, many not knowing what to expect.
Despite the cutting-edge technology the city is known for these days, there remain challenges for a first-timer in Seoul.
1. Traveling from the airport/around the city takes lots of time
Seoul is vast -- far greater than many expect.
As the largest proper city in the developed world, it's approximately 10 times the size of Manhattan, and much more crowded.
What this means for the time-sensitive business traveler is that a lot of buffer time should be factored in -- about 30 minutes, to be safe -- for getting to and from meetings, especially if they involve crossing the Han River.
From Incheon International Airport, the express train (? 8,000 or $7) runs every 30 minutes and will drop you off at Seoul Station, north of the river, near the Myeongdong business hub. Not a lot of travelers seem to know about this for some reason, and trains are usually quite empty.
Airport limousine buses (? 10,000-?15,000 or $9-$14) are another convenient way to get to most any destination from the airport.
Staffers at the airport's bus counter are helpful if you tell them where you need to go.
Cabs cost around ?50,000 or $48 to get into the heart of Gangnam (south of the river) or Gangbuk (north of the river).
During morning and evening rush hours, it's best to take the train.
2. The language barrier can throw you
The language barrier is particularly frustrating when it comes to addresses and directions.
Unlike the United States (or most other countries), Korea historically numbered buildings based on the date they were built in each district, not by location.
This means buildings next to each other can have completely different address numbers. (An initiative to change addresses is ongoing.)
The best way to get around is to have the address written or printed out in Korean to show to taxi drivers who can then input the address in their GPS system.
