I've stayed in two very nice LHWs: the Pan Pacific in Vancouver and the Ritz-Carlton in Naples, FL. Both properties had incredible five-star restaurtants onsite. Overall, both properties were among the best I've ever stayed in.
We got a room at the Pan-Pacific for about CN$250 through a corporate rate, and it was worth every penny and then some. At check-in, I asked about FF mileage affiliations. Not only did I get 500 UA miles, but the clerk also asked if I had any UA elite status. I had 2P at the time - upon showing the card, I got a complimentary upgrade to a mini-suite with a small living room and PC in the room. (I thought it was slightly ironic that this hotel valued my elite status far, far more than United itself does.)
The Ritz stay was a basic Ritz experience - excellent in every sense. The rooms were covered as part of a convention, so I didn't get any FF miles.
