If you've never been to Scottsdale, you have to check out Old Town at least once just to say you've been. It's true, it's super touristy, but that's why you should go, right? You're a tourist. Souvenir shops are the quickest way to get a summary of what an area is known for. It's interesting to just walk around and do some window shopping.
It's easy to find and parking is free.
