It's worth checking out, but remember keep your expectations low: For the cities in which I have upcoming hotel stays, the Hyatt sale rate is either not available for my dates (Jakarta) or is higher than my corporate rate (by 10% in Bandung and by 20% Hong Kong). And (as usual) the Hyatt flash sale rate is nonrefundable.
