Using the 48-hour Discover Seoul Pass, the zoolung feeding experience was great for the kids. The indoor area was comfortable with air conditioning, much better than Lotte, which requires a long wait. Riding the tour bus, my legs were tired, and I didn't want to get on and off. There happened to be a Squid Game event at Gwanghwamun. Although it was the last bus, it felt a bit sunny on the upper deck. At the end of June, it was still bright at 19:30. It also came with a 3-day eSIM, which is very cost-effective.
