I have not been there, but they are expensive. This weekend I am taking the family to Erie Pa. to Splash Lagoon. It may not have all the rustic appeal of great wolf, but the kids do not care. I have been to Splash Lagoon before, and a great time was had by all.
Don't know what part of NY. you are coming from but, I would check out splash lagoon in Eria if it is in resonable driving distance.
here is there website.

And for the record. I have nothing to do with the owning or running of the place.
