I don't smoke, but my mother does. If HAL were to ban all smoking she would not be able to cruise on HAL again unless and until she stops smoking. As it is, the restrictions on where one can smoke are extensive, and the staff doesn't always seem to know where one can smoke and where one can't from ship to ship.
For several years, now, HAL has been running the following survey on their ships:
They're even tracking our responses by coding each and every survey response to our name, stateroom number, booking number, and mariner number. I'm convinced that the restrictions on smoking areas that have been implemented over the last 2-3 years are the result of responses to these surveys. Rumors that HAL is about to ban smoking altogether are probably based upon the wording of this survey when read by someone who hasn't experienced it or responded to it many times over the past few years.
