Magnolia Terrace is a non-smoking building and convenient to the Main Building. I've stayed in each of the 4 Mansion buildings on 4 solo trips. Parterre Place is non-smoking, but it seemed like a longer walk. And it was the only Mansion where I had to go back and get a room change! Initially they gave me a "garden view" first floor room. Well, I was closer to the FQ than the Main building at POR and first floor garden view seemed like bushes for people to hide in. Although I love going solo, I learned then that I always get an upper floor room.
