**Update**
Here now. Just checked in this evening and did NOT get ANY of the rooms I requested for ANYONE in my party. Not only not the rooms, but we didn't even get the ground floor that I requested for a member of my party with a medical issue. I used Touring Plans to fax our requests and I called twice to follow up. I know none of this is a guarantee, but it's still disappointing.
Not to mention the CM gave me huuuge attitude when I asked about my requests. Her reply was something along the lines of, "I don't know why outside businesses tell guests they can request rooms because we do NOT have to do that and there's nothing I can do about it."
