Stayed at both last year.Hand down PH is far superior. Given the fact you'll be GH Melbourne it wasn't all that bad,RC rooms are average size and nothing special.RC Lounge was quite busy at Breakfast and Cocktail hours.Very average buffet in the morning with scramble eggs in a hot tray and the usual stuff, nothing fantastic.Cocktial at nite were fine ,but nothing that I can remember.All and all OK property but no star in the Hyatt chain.
