You can see quite a lot animals for only €12 each. You can also go to dive with sting rays with everything included. They also have big very nice shark tanks with an improving variety of species. Also if you take a walk straight through the first part of the aquarium you can go back later when there is less tourists. There is also an outdoor play area for the kids. You could easily spend all day here if you wanted.
