Should be able to get some good discounts this time of year but it will be hot. Sign up with golfnow.com for their email specials. Kierland is good but rarely offers a discount except for twilight rates. I like both of the courses (Faldo, Palmer) at the Marriott resort just to the north. Legend Trails is also nice but a long ride, near Cave Creek. These are just a few, no shortage of good golf courses in Scottsdale.
