Was HH Gold on my two stays at this property this summer so can't comment on Diamond perks, but breakfast in the restaurant is given even to Golds.

Be aware that overall this hotel is quite dated and rooms are very much in need of the upcoming renovations. I'm also hoping the renovations will address room noise problems from thin entry and connecting doors (it's so easy to hear guests in the hallway and in adjacent rooms talking that conversations are entirely intelligible). Also, currently many public spaces inside the hotel are being renovated, so there are noise issues with interior-facing rooms. I will probably try the HGI next time, despite the less "central" location, and hold off until the room renovations are done before considering giving this property a try again.
