One of the 2 airport hotels on Incheon island, where the Incheon Airport (South Korea's international airport) is located on. There are no tourist attractions around here on the island, but Seoul is just an hour by bus away. The hotel has a free ferry service from/to the airport. Take note though, it is not accessible on foot from the airport and cabs are very unwilling to drive to the hotel.
