I always have a #1 and a #2 room request added to my reservation when I book it. Sometimes I request a particular building, sometimes a particular room. I always preface my request acknowledging that I am aware requests are not guaranteed and CMs have always gladly added my requests to my reservations. I have never emailed or faxed my requests prior to arrival. I always POLITELY mention my request at check-in before they give me my room assignment and the CMs always tell me they see my request.
I have stayed at The Poly, Yacht Club, Caribbean Beach, and Pop Century and my #1 request has been granted all but once when my #2 request was granted. That was at CBR and, believe me, it turned out to be much better than my #1 request. Before I could even mention my request the CM said, "I am sorry that we could not meet your request but I believe you will be very happy with the room we have assigned you." WOW, was she ever right! That was my last trip to WDW, Memorial Day weekend 2007, and it is now my favorite room at CBR and it's my #1 request for my Dec. 2008 MouseFest trip!
As CleveRocks mentions, I've never been able to even get resort-specific info prior to check-in without being transferred to the call center.
I hope you are able to get the room you want at Pop. Let us know how it goes. Have a great trip to WDW.
