Scottsdale is a spread-out city, and having a car would be the easiest way to get around. However, if you don't have a car, there are plenty of ride-sharing options such as Uber and Lyft. Depending on your location, the cost can range from $10-$30 per trip. Keep in mind that traffic can be heavy during rush hour, so plan accordingly.
If you have extra time and are interested in outdoor activities, you can also visit the Desert Botanical Garden, the McDowell Sonoran Preserve, or the Salt River. If you're a golf enthusiast, there are plenty of golf courses in Scottsdale that offer stunning views and challenging courses. If you have less time, you can skip hiking at Camelback Mountain and spend more time shopping and exploring Old Town Scottsdale.
