Disney World has 2 really good water parks, blanking in the names

Another overnight trip: Moreys Piers in Wildwood, NJ. It's an outdoor facility (don't know if OP is looking for indoor or outdoor since she mentions GWL).

Hershey Park has a water park inside the park.

More for an overnight trip, there is Sandcastle in Pittsburgh.

OP here. This was not me. I'm looking for bigger water parks. Our sons loved Great Wolf, so something like that.

Do you mean the big commercial ones?
VA has smaller water parks, check here: http://www.nvrpa.org/
MD doesn't have much of the state run water parks.

Water Country?

/There are three open slides at Massanutten and an outdoor wave pool (after mem. day). There is also a big "lazy river" == that is fine for kids of all ages (assuming they are 40 in. tall or with a parent).

I'm looking for advice about great water parks within driving distance. We've been to Great Wolf Lodge, and the kids loved it. Preferably a place with a lot of open slides (meaning not the tube slides) and a wave pool.
