I wasted an hour wandering around and trying various inns and hotels, but they were all either booked or empty as ghost towns because of renovation. Very frustrating. I finally settled on the largest and most expensive hotel in the town: the Suanbo Sangnok Hotel. I ended up in a double room for W130,000 for one night. Ouch. At least the room has WiFi, albeit weak.
And for the fifth time in a row, I've been placed at the end of the hall. The place is a glorified love motel: sex noises (a woman's passionate moans) greeted me when I stepped out of the elevator onto the sixth floor. Fun.
