Great Wolf Resorts - if they end up building in Manteca - will not pursue a six-story hotel structure.Instead the firm that specializes in indoor water park resorts would cap the hotel portion at three stories. That is due to significantly higher construction costs in California than they expected for structures over three stories.Great Wolf Resorts, their Manteca project partner McWhinney Development, and the city has been in negotiations since December. The indoor water park-hotel combo is proposed next to Costco on 30 acres of surplus city wastewater treatment plant land.
