In the past when Oceania Cruises passengers were found smoking in cabins, a violation of the company's policy, they were given a polite warning to cease, according to the line. But now, under a new policy, guests who are caught smoking in cabins or on balconies will be notified they are to disembark at the next port of call. That's apparently in response to the fire on Star Princess. That fire is still under investigation but it appears initially a passenger's cigarette may be the culprit. Oceania is the first line to announce it will tighten up on smoking. For now others have not changed their policies, and many lines do allow smoking in cabins, including Princess Cruises.
