If the park is planning to grow (more attractions) this leads to more visitors. It's already full at the Kaiserplatz with the Wintertraum end show with the current amount of visitors. Maybe extending the Kaiserplatz (ground size) should be their priority. Once they are allowed to expand at all, of course.
I hope I'm allowed to respond in English 😅. I love to follow everything thats going on, but I do not speak German..
