I will state this upfront. I am a Marriott man. My school purchased the rooms for a conference. I was iffy about staying at a...ahem...Hilton. However, I was pleasantly surprised. I got a Jr King Suite with all the bells and whistles. Great water pressure; firm bed; great breakfast; great customer service.
Although I probably will not willingly switch my points over to HG, unless Paris calls me personally; I do suggest this one for any business travel warrior.
