No sprinkler heads on balconies...I don't think they can create that infrastructure. But certainly in the cabins. (trying to picture sitting on my veranda..nice thought by the way....) I believe Bob, the floors are concrete, railings steel and glass and of course, the ship is steel. The dividers, are of course, some type of plastic. I can't see a cigarette starting a fire on a Celebrity balcony ( again, picturing dropping a lit cigarette, or for that matter, starting a small campfire out there...can't see how it would spread with so much damp air and cement.....but I'm not up on other lines materials or sprinkler systems. I know all building codes for new construction (condo bldgs) have sprinklers in every single room, including the balconies.
But ya know what Bob? Fire is obviously not the point. They are banning smoking in all indoor venues, such as the champagne bar, which is why I won't sail them. They were already split up 50/50 on all public rooms and banned smoking in all dining venues and the theater. Why go to such extremes? I know I'm being redundant, but I just think it was really,really bad marketing move. Time will tell.
