In this episode of Schöne Ecken, hosts Sven and Cornelis document their visit to the Allrounder Mountain Resort indoor ski hall in Neuss. They begin by humorously correcting their location and setting up the adventure. The hosts discuss being invited by the hall and receiving equipment, while acknowledging ethical concerns about the hall's high energy consumption. They describe the hall's exterior as an industrial wedge-shaped structure and enter to find a faux-Alpine interior with wooden huts and a fake sky, which Sven compares to Las Vegas. Cornelis shares a traumatic childhood ski holiday where he spent a day falling repeatedly without lessons, and Sven recalls giving up skiing early due to impatience. Inside, they note the hall's dimensions: a 300-meter main slope, beginner area, and amenities like a climbing park and hotel. They rent gear, with Sven choosing snowboarding due to skateboarding experience. The hosts observe children on ski-bikes and the hall's controlled environment for learners. They take the chairlift without skis, getting an exclusive view from the top, and comment on the artificial horizon and ice cube decorations. Sven attempts snowboarding, describing his gradual learning process—braking, weight shifting, and eventual minor success—while Cornelis rests due to feeling unwell. They discuss historical trivia: the first ski hall opened in Vienna in 1927 with soda-based snow. Facts about the Neuss hall include 12 snow cannons, 9,000 cubic meters of snow, and 200 employees. In conclusion, Sven feels positively about snowboarding and the staff's hospitality, while Cornelis notes the cold and chaotic beginner area. They mention day ticket prices (39 euros weekends) and thank their technical assistant Lynn.
