A number of Hyatt Platinum and Diamonds have emailed me that they have gotten these.
They show up as "Renewal 2010 Free Night Award" in the promo awards section of Hyatt.com
It appears to be targeted to those who don't stay at Hyatt too much (not me!)
I opened up a Hyatt account for my father last year and made him trial Plat and he got 2 of these! He had no qualifying stays.
I called Hyatt hoping to "get targeted" and they said no soup for me...
Any forum readers get one?
