The project opened in December 2018 as The Alder at Resorts World Catskills. In mid-2018, construction began on the Entertainment Village, a building next to the casino containing retail space, restaurants and 105 hotel rooms. The property was originally to be named Montreign Resort Casino but announced in April 2017 that it would instead license the Resorts World name from Genting Group, the majority owner of Empire Resorts. The property features 65,000 square feet (6,000 m2) of gaming space with 112 table games and over 2,150 slot machines, and an 18-story hotel tower with 332 suites.
It was built on the former site of the Concord Hotel. It opened on February 8, 2018, and is owned and operated by Empire Resorts. Resorts World Catskills is a hotel and casino located in Monticello, New York.
