If you buy a pass ticket, it's best to enter around 9 a.m., or 10:30 a.m. at the latest, so you can explore all the rides.
Overall, the rides change every few years.
But I think the rides are currently geared towards children aged 7 and up, with a certain height and age.
For children under that, there are fewer rides available.
