Most certainly the smoking issue on cruise ships is pretty contentious. If one has doubts just look at the HAL smoking only issue thread on C.C. Over a quarter of a million views and working toward 3500 posts. Some of those folk would come to blows if not separated by cyberspace, Haw. That thread was more or less generated due to all the global major cruise lines, except HAL, discontinuing their smoking on balcony policies, the big 12 to be exact. Thereby creating a situation wherein smokers began leaving their cruise lines of choice in favor of HAL due HAL's more lenient smoking policy.
Personally I don't get my knickers in a knot over the smoking stuff, other than we dumped HAL almost two years ago now due balcony cigar smokers. I never smoked however my wife did, quit about 25 years ago, she is like one of those "Born again Christians" Crusin Tim mentions, even to this day she says that if someone ahead in stopped traffic flips a lit cigarette out the window she has to control the impulse to leap out and start smoking it.
Actually, I welcome having a pipe smoker on the adjacent balcony. An occasional cigarette doesn't upset me either. But since we usually book long voyages getting stuck with a cigar smoker is too much. Worst case scenario is what one HAL guest experienced, they had a cigar smoker on the adjacent balcony, but what really made it bad was that he would invite his cigar smoking buddies to join him. Now, if there had been a smoking lounge on that HAL ship chances are the little group would have gotten together in that venue.
Some of us have been discussing for some time that HAL is unlikely to be able to prohibit balcony smoking, under the circumstances they now find themselves in, unless and until they have interior areas dedicated to smokers on all their ships, like they do on many other lines, for example the Churchill rooms on Princess and Cunard or the Connoisseur smoking rooms on Regent, Carnival and other lines. HAL has only one ship with such and their newest ship is coming out without one, to do so for their entire fleet will involve a lengthy and expensive undertaking.
Anyway, I stand by my assessment that Celebrity appears to be closer than anyone else to becoming smoke free. I've never been on Celebrity but base my opinion on all the areas they prohibit smoking entirely in, particularly the casino, on balconies and that Celebrity does not even provide a single smoking room dedicated to smokers, yet their guests appear to give them near unanimous approval. Be interesting to learn of another line that tops that.
