St. Regis Hotels generally maintain a non-smoking policy in most public areas and guest rooms to ensure the comfort and health of all guests. However, specific policies may vary by location, as different properties may have designated smoking areas outside or specific floors that permit smoking. It is recommended that guests check the individual hotel's smoking policy upon booking or upon arrival for the most accurate information. St. Regis Hotels aim to provide a luxurious and enjoyable experience for all guests, and adhering to their smoking policies is part of that commitment. For the latest details regarding a particular St. Regis property, it is a good idea to visit their official website, where they provide comprehensive information regarding their policies and amenities.
