We also always make NS our #1 request.
We've been members since '93 and only got a Smoking unit one time. (About 2 years ago). We checked into OKW late on a Sunday (about 9:30 pm) and only two 1-B/R villas were left, both of them smoking. MS sent housekeeping over right away and she used Febreez all over the place, then left the bottle with us for the remainder of our stay. That helped a lot.
