Not specific to WL, but I do two things when I have specific room requests: I email DSS, and I also make a request on Touring Plans. Between them, one will be received. The latter is good about requesting a specific facing direction, and you can also include specific comments (e.g., using the q’s about the Poly just asked, “If possible, we’d like the following, in this order of priority: 1) a 3rd floor room and 2) a room with a walk-in shower. Thank you!”). Don’t forget the thank you

. I have had decent luck - although admittedly, my requests tend to be more avoidance of certain individual rooms or characteristics.
