ADG to Design and Build the New Indoor Waterpark at the Montreign Resort Casino at Adelaar

Proposed water parks could make a big local splash

Call it the wild card of the casino sweepstakes.

While all eyes are focused on the Montreign Resort Casino at Adelaar as a future economic engine, another potentially game-changing industry is making waves among local developers and officials: indoor water parks and their 300-plus-room hotels.

Adelaar has long been planning an indoor water park and a 350-room lodge on its 1,700 acres just outside Monticello, to be built by the same company that just built the Northeast’s largest indoor water park in the Poconos of Pennsylvania.
