So I called just now with this information in mind. The reservation cast member said that she can only request that we get a building near the main building, but not request specific building numbers. I have never heard that, in fact all the advice I have ever read said to ask by the building number.
WOW, When I booked mine just a little over a week ago, the CM I spoke with put in the building I want in the comments. This is what it looks like on my reservation.
