Just heard about this over the weekend. I never saw the survey where the owners apparently voted overwhelmingly in favor of the smoking ban. If I owned here and was a smoker, I would probably be pretty angry.
That being said, I own here and am a nonsmoker, and I am thrilled with this development. We have been stuck in a smoking room more than once, and this is now something we won't be faced with, either here in the US at the hotels (which went nonsmoking in September) or, now, while in Aruba.
My only concern is that the beach will be even more overrun with cigarette butts than it already is.
