I know there is no smoking allowed in the dining rooms. I don't believe they allow smoking in the show rooms either. You may smoke in sections of the bar/lounges.
Smoking is allowed any where in the casino.
Well I am a smoker but very careful not to smoke in places that would offend others. So on our last NCL cruise I went into the casino to have a smoke. (lots of smokers there) I bought a roll of quarters and sat by a slot machine. Was towards the end of my cigarette and still lots of quarters. Put three in the machine and pulled...Oh to my surprise when I hit a jackkpot. The pay out was $2,500.00 Since I just have no enjoyment in casino's I collected my winnings put my cigarette out and left. 2 years later by husband still tells the story about the look on the dealers face when I did not stay to gamble away my winnings!!!
