I haven't ever found the amount of smoke that drifts over from another room's balcony to be enough to be bother me and I've got seriously impaired lungs. Smokers have to have a place to smoke. Now that smoking rooms are becoming ever rarer, smokers start to seek out hotels with balconies and windows that open. Smokers are not going to be able to go even a one night stay without a cigarette, no matter if the hotel is supposed to be entirely smoke free. Let's be realistic and allow smokers with viable alternatives to polluting the non-smoking rooms.
