Many SC16 hotels are located within a few blocks of the Convention Center. Others are located near the Salt Lake City Airport for convenient arrivals and departures. A few others are located near the University of Utah campus. Bus transportation will be provided to/from any conference hotels farther than .5 miles from the Convention Center.
The good news about Salt Lake City hotels is that they will be significantly cheaper than they were in Austin last year for SC15.
If you are choosing your hotel from map, please note that the city blocks in Salt Lake City are huge. What may look like quick walking distance can wear out your shoe leather.
