I don't know what your timetable is like, but we always put our luggage out the night before and then stay on the ship as long as possible. This makes getting an elevator easier. Also, you might consider using forward or aft elevators and going to the appropriate debarkation floor, as the central elevators always seem to be the ones that are the busiest. We did just debark off the Spirit and went down during early debarkation, though, and had no issues whatsoever.
