Our first two trips we were happy with the room that was assigned to us, but this year we want to request a ground floor in buildings on the old side. When we checkin do i ask for specific room numbers? Building numbers (as per map)? Just say "ground floor old section"? What has worked for you?

Does it hurt to list this on the pre-checkin form?

If flights are on time i would assume we will be there well in advance of when room is ready. I am hoping this gives us an advantage in a room request at checkin.

Thanks,
Rachel
