Whether Resorts World is "21 and over only" depends on which specific property you are visiting and which areas you intend to enter. In Las Vegas, Resorts World Las Vegas is generally open to all ages for hotel stays, dining, and shopping; however, you must be 21 or older to gamble on the casino floor or enter specific bars and nightlife venues. Similarly, at Resorts World Catskills in New York, the gaming floor is strictly 21+, but the resort features family-friendly amenities like pools and certain restaurants. At Resorts World New York City (the racino in Queens), the minimum age for gaming is also 21. While the hotels themselves welcome minors, the "resort experience" is heavily skewed toward adults due to the gaming focus. Guests should always carry a valid photo ID, as security is stringent at casino entrances. In 2026, many properties have expanded their "all-ages" dining and entertainment options to attract a broader demographic beyond just gamblers.
