I have some of the above awards (cat 1-4) in my account. As I tried to apply them today to different Hotels that I am interested in, the Hyatt site showed no availability (only the high guaranteed rate Rooms are available + using GP points and Elite rate, etc. Awards expire by July 31st. What are your experiences using the awards? Am I the only one that choose free nights over points? I am posting this from Asia and look for availability mainly in Europe and Asia.
