I asked this question a few weeks ago, and some helpful posters told me that although they were in smoking optional rooms they could not smell any smoke because the mousekeepers do a great job in cleaning the rooms and getting rid of any smell of smoke left behind by previous guests.
Now, if you're asking if you can smell the smoke in the hallways and under the doors and from the balconies, I'm not sure about that. I would assume that all of the nonsmoking rooms would be together and all of the smoking optional rooms would be together to reduce the likelihood of smelling smoke if you're in a nonsmoking room. But, I'm not sure. Anyone??
