As those of us who are repeaters know, we need to book the room we want, not the room we want to upgrade from, as the upgrades are few. I guess that happens when a resort is popular or you travel during a popular time. One thing I think would be a good alternative is during our pre-check in if we could give a preference, not of room, but floor, building or something along those lines. For instance for CTI we could say first choice--Building 4, 5th floor, 2nd Choice Building 2, 3rd floor, 3rd choice etc. It still would be based on availability, but it may be more likely to happen than the upgrades. Just my opinion.
