I have been there last year, it was nice to make the children play in the cold winter time. Nice swimming pools with slides and small artificial waves. It was a bit expensive but it was OK for once.
BUT last month I have tried to go, the management changed, for a family with 2 children, it would cost me about 100 Euros, just for the entrance.
I left disgusted... up to you if you want to try to negotiate a better rate.
