Carnival Cruise Line has increasingly prioritized the comfort of non-smoking guests by introducing smoke-free casino options across its fleet. While many of the older or traditional ship designs feature a single casino with designated smoking and non-smoking sections, newer vessels and recent refurbishments have shifted toward more robust separations. For example, the Excel-class ships (like the Mardi Gras, Carnival Celebration, and Carnival Jubilee) often feature entirely separate non-smoking casino annexes to ensure a fresh-air environment for players. Additionally, certain ships, such as the Carnival Splendor, have tested entirely smoke-free casino environments. Most ships now provide a dedicated space where guests can enjoy slots and table games without exposure to secondhand smoke. However, policies can vary by ship and itinerary, so it is always recommended for guests to check the specific deck plans for their vessel, such as the Carnival Festivale, to locate the designated non-smoking gaming areas.
