I am looking to book an award 5 night stays at Hyatt Centric Ginza for my wife and daughter for this summer. We have just earned a Guest Honor and Suite upgrade award. Here are my questions:

• Does Hyatt Centric Ginza has a standard suite so I can apply this suite award certificate? If someone can point out a way for me to figure it out for each property, it will be very much appreciated.
• Does it make sense for us to use the Guest Honor certificate for this stay in your opinion?

I also have a two room paid stay next month at Park Hyatt Seoul via Virtuso for six nights? In your opinion, does it make sense for us to apply one of these awards to this stay instead? (Or it cannot be applied retroactively?)
