The place seems to be normal. But there is a huge impression that the staff here is recruited from people with disabilities suffering from deafness. (There are places where such people are specially taken)
So this is the place.
In general, the place is normal. Even the deposit is refunded, just very loud music.
The water park is considered a place of entertainment for children, and the staff plays music with elements of a MAT. In general, think for yourself.
