The Hilton at Resorts World Las Vegas follows a strict non-smoking policy for all guest rooms and suites. If a guest is found smoking in their room, a deep-cleaning fee (typically $500 USD) is assessed. However, the broader Resorts World complex is a "hybrid" environment. While the hotel lobbies, retail areas, and most restaurants are smoke-free, the casino floor does allow smoking in designated areas, and there are specific outdoor smoking zones located throughout the resort. In 2026, the resort utilizes advanced air filtration systems to minimize the drift of smoke into non-smoking areas. For guests who are highly sensitive to smoke, the Hilton and Conrad towers are generally the best choices within the complex, as they are situated furthest from the main gaming floor where smoking is most prevalent.
