We stayed in a one-bedroom and a studio in BWV in November/December. We were very impressed with the condition of the one-bedroom, non-smoking unit w/boardwalk view (I think it was number 3041). However, later when we switched to a studio, it was a smoking unit and was in dire need for some repairs, a good scrubbing, and a new coat of paint (it was room number 2031).
So, I guess the moral of the story is that some units are better than others, however, if you are a non-smoker you probably want to make sure and get a non-smoking unit. Although the studio we were in was dirty, mildewy, and such, not just the typical "cigarette burned" smoking unit.
