Really nice amusement park with free rides for the little ones and a variety of restaurants (nothing fancy, but enough).
40 will provide you with 6 tokens for rides, but I assume that the day pass is better value if you want to go through all the attractions.
I believe it is open until 11pm and after 8pm tickets are cheaper, but some free attractions like the Panorama will close by then.
Good for a day out with the kids and as I said, since there are quite a bit of free rides for them, you may not need to spend an euro on it.
Did I mention that it is free entry?. Not many of those around these days.
Highly recommended.
