I have stayed at both hotels many times -- with the FFN promos going I bounce back and forth. They both have distinctive pros and cons. The HR is much quieter, a bit more "homey", the RC is MUCH quieter and has free high speed internet, closer to Hakata train stain (easy walking even with roll-away) about three blocks, the windows in each room open; better breakfast buffet (if you don't have access to the RC). The GH is in a much more interesting area adjacent to huge shopping/entertainment/eating complex (and closer to "downtown"), bathrooms are GREAT, RC charges Y1000 for high speed internet use, room itself is slightly smaller than HR, but very nice; about twice as far from Hakata -- certainly walkable, but more of a jaunt; very nice food court in basement with fairly upscale selections; staff speaks better English. All in all given a one time choice I would do the GH. Fell free to email me with other questions.
