In 2026, almost all major cruise lines have strictly prohibited smoking on stateroom balconies due to significant fire hazards and the discomfort it causes to neighboring guests. However, there are a few notable exceptions among international and niche carriers. Costa Cruises and Fred. Olsen Cruise Lines have historically been some of the only operators to allow smoking on private balconies. Most other giants like Royal Caribbean, Carnival, and Norwegian (NCL) will levy a "cleaning fee" of $250 or more if you are caught smoking or vaping on your veranda. For smokers in 2026, the standard is to use designated smoking areas located on open decks or in specialized cigar lounges. It is vital to check your specific ship's "Guest Conduct Policy" before boarding, as even the few lines that currently allow it are facing increasing pressure to ban balcony smoking entirely for safety and environmental reasons.
