The park is super fun, you have to have lots of energy. Its safe, the staff helps you with the advices and suggestions.
It is also expensive, especially if you know you will be there only once - because you have to pay the entrance + bracelets + socks. For a family if 4 it this almost 90 eur.
there is also a bar where you can hang out, it has reasonable prices and a view to the park.
