I used online checkin last week. My only choices were close to main building/transportation and first floor. I only had a standard room booked. But it gave me no option to put in specific room requests. I had requested building 4 or 5 (yeah I know no standard rooms there anymore but it never hurts to try) so I figure I might have a chance, but we'll see. Of course there was a computer foul up and I had to call and they gave me a direct website to go to instead of using the links on the WDW website. Don't know if that changes anything.
