Upon arrival at the Salt Lake International Airport, you have three options to travel to the University Guest House:
(1) Taxi (approximately $30)
(2) Light Rail ($2.35, http://www.rideuta.com)
Take the Airport Light Rail (Green Line), transfer to the Red Line (University direction) at the Courthouse Station, and get off at the Fort Douglas Station. Walk across the bridge, and you will see the University Guest House on your left.
