While I actually like the Scottsdale Resort....there isnt a whole lot within walking distance. There is a mediocre mexican restaurant across the street and a mediocre steak house as well and a small strip mall. You can walk to Houstons which is down the street on the same side as the hotel and it has a little better food. For a couple of nights it wouldnt be too bad but I would much prefer to go to some of the better places in Scottsdale which is not within walking distance. How do you plan on getting to the conference each day, do they have a shuttle? I would recommend a car for the whole trip as it would be cheaper than taxi's and the weekly rate would probably work out better in your favor anyway.
