Nor should they be as PHs have an understated minimalist modern design ethos while GHs tend towards a more standard high end design that embraces opulence over starkness. I have no complaint about either and appreciate having the possibility of experiencing different decor styles when staying at Hyatts in the Pacific region. That's why I decided to do Hyatts when my travel pattern shifted from the Atlantic/Europe to the Pacific/Asia. Loved both GH and PH in Shanghai, less so the HotBund.
