I do favor perhaps a section of the ship with smoking allowed cabins. I think the crews do an incredible job of cleaning - I have never noticed the smell of smoke in one of our cabins, and quite frankly not really much walking through an empty casino. But I would rather not have my neighbor's smoke wafting onto my balcony it is unpleasant.
All I ask is a tall ship and a star to steer her by; John Masefield
