Hyatt fancies GH as luxury, while HR is upper-upscale. That really is the extent of it. Now, I don't think among self-described Luxury brands that there is any disagreement that GH is the lower-end of these brands (compared to Andaz or PH), but the purpose of the GH brand is clearly to differentiate that you should expect more at a GH than the nearby HR. And I agree for the most part from my experiences in the US (DFW, Atlanta, Washington DC, Denver, San Fran). Not that there isn't going to be some preferences that go the other way, but when I am booking hotels, I am expecting more service and finer finishes at GHs compared to HRs and indeed the GHs usually deliver.
