Duckielucky must be very sensitive to smoke, and I know there are people like that. My son is very reactive to it and he didn't have any issues on Deck 9, nor did my slightly finicky, always-looking-for-something older mom who came home after 2 weeks away from our house when I was a teenager, and immediately asked which of my friends had lit-up in our house! (OK, so one person lit one ciggarette, which I immediately had them extinguish - and somehow she instantly knew!) At any rate, while I do believe that some people may have trouble if they are sitting close to someone smoking on Deck 9, in two cruises I haven't detected it, unless it was right next to me.
