This had been on my radar for years, but moved up a notch or two when it became a Hyatt, so I gave it a try on a recent trip to Phoenix.
I like old and historic, but the casita I was given as an upgrade felt frumpy to me, and there seemed to be a problem getting hot water. As it was a hike from my room to reception, I was surprised not find a bottle or two of water in the room (it IS the desert, guys). I was even more surprised not to receive turndown service. Housekeeping was generally bad--the maid knocked on my door at an unacceptable hour on the day I was checking out to see if she could clean the room, and when I said no, demanded to know when I was leaving.
I'd heard very good things about the restaurant, T Cook's, and had a good, but not great, dinner there.
Over the years, I've probably stayed at 6 or 7 resorts in Scottsdale/edges of Phoenix. I'd rate this one on the low end of that scale.
