We had planned to use it at night, but my family was very tired, so we moved it up to around sunset. There were only four of us on the cruise—my family and one other gentleman—so it felt like a private cruise, haha! The guide gave excellent explanations, and the City cruise had the best facilities. The person assisting us spoke Korean so well, I wondered if they were Korean, which made things very comfortable. A cruise offers a different kind of scenery than walking around, so I highly recommend trying it at least once!
