Globally, It looks like most people still have trouble recognize the different hyatt brands, but after interpretation which GH and Hyatt are different word , it looks like Grand Hyatt is even more recognizable than Hyatt or HR in China/Hong Kong markers and mostly are built GH brand in those area. People there have no problem about this, I would say this have something to do with marketing in different area.

It's really a nice discussion to see those wonderful comment here
