What is the DVC discount for Disney Quest and the water parks?

[edk35]

I see gate price at each is approx. 40 bucks and was wondering how much of a discount do we get as members on a one day ticket. I also see that there is an AP just for water parks that runs about 100 (no dvc discount) and is just for the water parks. I am trying to decide if I want to get PAP for my dh and boys so they have the Disney Quest and water parks. We are getting new AP's in Jan. and will use them in July and they will probably go to the water parks a day or two in July. Thanks
