The Little America Hotel (our YAPC::NA::2015 — Salt Lake City venue) is located near the south portion of downtown Salt Lake City, Utah. While the area is walkable, often it’s easier to hop onto the TRAX light rail for a stop or two. Rides in the downtown area are free as long as you stay in the Fare Free Zone.
Here’s an example: The City Creek Center is a beautiful, centrally located indoor/outdoor mall with restaurants, shopping, and lots of activity. It is about 0.8 miles from Little America, which would take about 20 minutes at a leisurely pace on foot. But you can jump on the Green Line or Blue Line Trax light rail for two stops, free, and you’re there quickly without breaking a sweat. The light rail trains are spaced just a few minutes apart and typically run until around 11:30pm.
The YAPC::NA::2015 wiki provides details for this and other transportation options. Have fun in Salt Lake City!
