Winter Water Parks?

I ran into this site the earlier and I thought I should post it.  It’s an indoor water park just off 295 in Mt. Laurel.  So yes, you can visit waterparks in the winter.  The place is called Cocokey, it’s connected to a Marriot Hotel.  I think they want people to look at it more as a resort than a one day trip.  I haven’t been there myself, so if anyone could fill me in on some details, ere I venture over, that’d be great.
