Wynn Las Vegas allows smoking, but it is strictly regulated to ensure a "gold standard" experience for both smokers and non-smokers. In 2026, smoking is permitted only in designated areas, which include the main casino floor and certain bars and lounges that are equipped with high-end ventilation systems. However, all guest rooms and suites at Wynn and Encore are strictly non-smoking; if a guest is found to have smoked in their room (including the use of cigarettes, cigars, or vapes), the resort will charge a significant "deep cleaning" fee that can exceed $500. Additionally, smoking is prohibited in all "public" indoor areas such as the hallways, the retail esplanades, the theaters, and the majority of restaurants. For those who prefer to smoke outdoors, there are specific areas near the pools and entrances where it is allowed. The resort utilizes advanced air filtration technology to minimize the "second-hand" impact on non-smoking guests, but the general trend in Las Vegas continues toward more restrictive policies, so it is always a good idea to check for updated "No Smoking" signage upon arrival at any specific venue within the property.
