I stopped smoking 6 weeks ago. Haven't desired a cigarette since then after smoking for 25 yrs. I won't be staying at this hotel anytime, though. There are other places to stay that appreciate peoples business.
I can think of maybe one stay at a Westin in my 50 years, so I'm not likely to be patronizing them soon. However, I wouldn't have a problem doing so, as this is a free business decision on their part. No one is forced to stay there, nor are they prohibited from staying there. They are, after all, providing an outdoor designated area.
