The open house is planned for Thursday in Goshen in Orange County, where the amusement park based on the popular plastic construction toy would be built. The county had tried to lure developers for months after Legoland scrapped plans last year to build in neighboring Rockland County.
The open house will give residents a chance to see a model of the park and to ask questions.
Legoland theme parks are located in California and Florida. They also are in Denmark, England, Germany, Malaysia and Dubai.
