I Love Marriott.
The more smokers that get pi$$ed off and decide not to stay, the less chance I have of standing or sitting beside one and smelling their smoked filled clothes.
I'll be willing to bet that Marriott's occupancy rates are climbing as more and more people learn of this nonsmoking policy. Now if they can institue a similar policy against pets, it will even be better (save for extended stay resorts).
IMHO
