Really interesting (and slightly bizarre) to log in a few times a week and see how the potential options for suite upgrades appear to change daily.
I think I have about 6 outstanding reservations left for 2012 currently. Over the past 3 weeks, at some point NONE of them were eligible for upgrade in advance, but at other times half were. Some properties seem to come and go, depending on when one logs in. Really odd.
Sometimes the upgrade options are nothing more than Club Room, while other times it's 1500 ft sq master suite.
