I have an upcoming trip to Japan and I'm planning to use points for Free Nights. I really only have enough points for 2 - 3 nights depending on which property I choose but I'm debating between the Park Hyatt and the Grand Hyatt and whether it's worth to book as "Standard Room" or "Regency/Grand Club".
The Grand Hyatt website is pretty clear about what is included when booking a Grand Club room but the Park Hyatt site really does not make any reference that I could find.

Can anyone tell me what the differences are if booking a "Regency/Grand Club" vs. "Standard Room" at the PH?

I am just a basic Gold Level member FWIW...
