I have to say it was totally off-plan. I was just going to buy something at Lotte World, but when I saw it, I wanted to go up. When I got there, I really wanted to go, so I talked to my friend and bought tickets through Klook (great price). Getting up there using Klook was super fast; the money was debited instantly, and they sent me a QR code right away. And we didn't hesitate; we went up immediately. The view from the top was beautiful. There weren't many people when we went up, maybe because it was a weekday, so we could see everything. I was able to take pictures from every angle. The organization up there was good. There were spots to take pictures with mirrors and on the glass floor, and you could go outside to feel the breeze. It was worth every penny; I loved it. My friends loved it too.
