I was looking at the Pop Century map with the smoking areas noted on it for an upcoming trip I'm taking with smokers. I think there are plenty and within short walks from the buildings.
However, as a non smoker, I know that this world is NEVER going to be smoke free. Not at Disney World, not in my real life, not even going into a hospital (where the smoking area is right outside the main door). I can't drive and have a totally smoke free experience. I can smell when someone in the car inf ront of me is smoking, even with the windows rolled up.
Will there be people who don't care about Disney's smoking policy? Of course. When people are outside, they sometimes don't see the need to be careful about their smoke. After all, it's outside, the smoke doesn't stay around. That's why you will sometimes see people standing right outside their door smoking. It's outside.
Almost all the times I've been confronted with a situation where a person was smoking where they weren't supposed to and it bothered me, I have politely asked the person to move to a designated area. Sure, Disney's resort are smoke free. But people think it's only the ROOMS that are smoke free. They don't realize it's the grounds as well.
I don't smoke, never have smoked, never will smoke. However, until the nicotine addiction is forever more wiped off the face of the earth, we're all going to have to co-exist.
