Are there any ATMs or currency exchanges on the transit side of Incheon Airport? We're passing through but are staying overnight in the transit hotel. Is there anywhere to get won from on that side, or will we be limited to credit card usage if we don't bring our own?
From the Lonely Planet forums:
Transit passengers who do not clear customs will not have access to any ATM in Incheon Airport.
The only ATMs at Incheon airport are outside the sacred circle of customs. So if you need cash when you land at Incheon, you have to clear customs.
There are two currency exchanges on the transit side that will exchange money into Korean won, as well as most stores/restaurants accepting US dollars and some other currencies.
