The few things that "stood out" to me where the increase in points for arrival gift at CY to 400 points in US/Canada. As posted earlier, nice - but why not the more expensive international properties? (and seriously, still no points on incidentals at Courtyard?!)
It also has been officially communicated that platinum elites have free access to the "premium" internet service at all the mid-range brands that are now offering tiered internet (don't remember that being "official" before)
