Yes, I always get a non smoking building because of asthma. But just so you know, it doesn't always stop anyone from smoking in their rooms. The person was smoking in the room next to us, and it came in (as it always does) through the bathroom vent (we try to keep our exhaust running as much as possible, but it shuts off when we are out of ht eroom, so we often come back to the smell). I talked to one of the people in the room, as they exited and mentioned it was a non smoking room, and she just stared at me as if she had no idea what I meant (she spoke English, because she often went outside of her room to talk on her cell). I called the front desk, and while they thanked me for reporting it, did nothing. I called a second time and they offered to send housekeeping to "desmoke" it...a lot of good that would do, with the smoking still going on. Non smoking buildings also only mean in the room, so many people smoke out on the balcony/walkway. Just no way to get around it, and still travel to Disney.
