Wow, there is a lot of bile spit back and forth for what equates to be a pretty simple answer... One word, and Lee already threw it down...
Economics
If Disney thought it could make more money catering to smokers, then you would see smoking buildings, increased designated smoking areas, etc... But as it stands, it seems the money is garnered by catering to the non-smoking crowd... Is it a pain for smokers? Sure, it can be... But, I have a feeling that the dollar is going to speak here, and choosing to go non-smoking is a carefully researched, thought-out and planned decision which will incur more profits for the company...
So, whether you feel smoking is right or not... Whether you think smokers are killing themselves or killing you... Whether or not smoking makes you sick to your stomach... Whatever pseudo-science EPA-produced thrown-out by the supreme court study you produce... It doesn't matter...
Disney is a private company, and will do what it thinks necessary to increase its profits.
If you don't like it, send a message by not giving them any profits and be sure to let them know WHY you didn't go a second time this year... or, conversely, if you do like the decision, and think that smokers are the spawn of the devil, then upgrade to a better resort knowing that the area you stay in and the air you breath will be cleaner and safer... and be sure to let Disney know that you are maybe spending an extra day at Disney because you know that they are looking after your health and well-being...
There is simply no need for the vitriol that every single smoking thread on this board produces. If you smoke, then enjoy the relaxation you get when you take the first puff, I did for several years at almost a pack a day. If you don't smoke, rest easily knowing that your favorite vacation destination just became a bit more accomodating for your desires.
But this is the land of the free, if somebody wants to smoke, then that is their right, as long as they follow the established rules of the location they choose to attend.
