This boutique hotel, which opened in January, aims to attract a more youthful clientele with the same luxury experience offered at the main casino hotel, but on a smaller scale and price point. And just down Resorts World Drive is The Kartrite Resort & Indoor Waterpark, New York’s largest indoor waterpark. The Alder at Resorts World Catskills, a 101-guest room boutique hotel, joins the resort’s main all-suite hotel. Two new properties have opened on the Resorts World Catskills Casino Resort campus within the past six months.
