According to the regulations of the Costa Selena cruise ship, smoking is prohibited in both the cabin toilets and public toilets. Smoking in these areas may trigger smoke detector alarms and may cause the cruise ship to take appropriate emergency measures. In addition, for smoking on the balcony, if there is no dedicated smoking room, you can only smoke on the balcony.
In summary, it is very important to comply with cruise ship regulations in order to ensure the health and safety of passengers and others. If you have any questions or require further information, please refer to the cruise ship's official website or contact the cruise ship's staff.
